The exercise below has to do with arithmetic progressions and or arithmetic sequence.

<h3>What is an Arithmetic Progression?</h3>

An arithmetic progression is a sequence of numbers where the difference between each consecutive term remains constant as the sequence progresses.

The next three terms  and the rule for finding the <em>nth </em>term in each sequence is given as follows:

A) 1.1,4,9,16,25,36.

The rule for finding the <em>nth </em>term: square each term in the arithmetic series 1², 2², 3², 4², ....nth term = n², etc to get the present term in the sequence.

That is:

1, 4, 9, 16, 25, 36  =   1² 2² 3² 4² 5² 6²  

To get the next three terms, we say:

= 7², 8² , 9² =  49, 64, 81

hence, new number sequence  1 , 4, 9, 16, 25, 36, 49, 64, 81.

B) 3, 5, 7, 9,

The rule for finding the nth term here is the Rule for finding the <em>nth </em>term: 2n + 1.

Hence:

3 = 2 (1) + 1 = 3

5 = 2 (2) + 1 = 5

7 = 2 (3) + 1 = 7

9 = 2 (4) + 1 = 9

Therefore the next three terms in the sequence will be arrived at as follows:

2(5) +1 = 10 + 1 = 11

2(6) + 1 = 12 + 1 = 13

2(7) + 1 = 14 + 1 = 15  

The updated number sequence is 3, 5, 7, 9, 11, 13, and 15.

C) 20, 16, 12, 8. The next three terms is gotten using the rule (20n-4n). That is:

20 - 4 = 16 =   [20 - 4(1) ]      

16 - 4 = 12  =   [20 - 4(2)]

12 - 4 = 8    =  [20 -  4(3)]. Thus the next three terms are:

[20 -  4(4)] = 4

[20 -  4(5)] = 0

[20 -  4(6)] = -4

Hence the updated number sequence is:
20, 16, 12, 8, 4, 0, -4

Reread lines 20-21. What is the meaning of these lines in terms<br>of Whitman's extended metaphor?​
Sliva [168]

Answer:

In "O Captain My Captain" by Whitman, The extended metaphor of the poem compares President Lincoln to a captain steering the "ship of state" which means guiding the union through the civil war.

Explanation:

An extended metaphor means; A metaphor that unfolds across multiple lines or paragraphs of a text, making use of multiple interrelated metaphors in an overarching one. The "captain' of the title however, becomes less essential to the progressive success and unity of the nation as it seemed in the beginning. because at first the "captain" (President Lincoln) is seen as entirely responsible for the safe return of the ship home.

But, the citizens continue to rejoice after their captain has fallen, they did not let the grief of the assassination on the president stop them from continuing their celebration as well as moving on with their lives.

Can you help me make up a story about my character that says? You are a 27-year-old devout nun who enjoys rock climbing?
Aleksandr-060686 [28]

Answer:

Explanation:

The best-known citizen of the Indian hill town of Darjeeling, Tenzing Norkay, is in residence now, though unseasonably, for the year’s climbing in the Himalayas has begun and most of his Sherpa colleagues are off helping Westerners up the peaks. His presence reflects the change that has taken place in his affairs since May 29th of last year, when he and Edmund Hillary stood on the summit of Mount Everest. That feat earned Tenzing a rest from his career as a climber, which had been arduous, and plunged him into a new career, involving contracts, publicity, and politics, which is a good deal more lucrative but which puts him under another kind of strain. Not only is he, like many famous men, unschooled in the ways of publicity but he deals haltingly with English, its lingua franca. Just keeping track of his own life, therefore, demands hard concentration. Tenzing complains that he has lost twenty-four pounds since climbing Everest, and he says—though he probably doesn’t mean it—that if he had foreseen the results, he would never have made the climb. His troubles are compounded by an element of jealousy in Darjeeling—he is to some extent a prophet without honor in his own country—and by a public disagreement, which he is well aware of, as to whether he is a great man or only an able servant. “I thought if I climbed Everest whole world very good,” he said recently. “I never thought like this.”

Tenzing is at everyone’s disposal. He has fixed up a small museum in his Darjeeling flat, exhibiting his gear, trophies, and photographs, and he stands duty there from ten in the morning to four-thirty in the afternoon. He is a handsome man, sunburned and well groomed, with white teeth and a friendly smile, and he usually wears Western clothes of the Alpine sort—perhaps a bright silk scarf, a gray sweater, knee-length breeches, wool stockings, and thick-soled oxfords. These suit him splendidly. Redolent with charm, Tenzing listens intently to questions put to him, in all the accents of English, by tourists who come to look over his display, and answers as best he can, often laughing in embarrassment. He charges no admission fee, but has a collection box for less fortunate Sherpa climbers, and he seems to look on the ordeal as a duty to the Sherpas and to India as a whole. The other day, I, who have been bothering him, too, remarked on the great number of people he receives. “If I don’t,” he answered, “they say I am too big.” And he scratched his head and laughed nervously.
