Answer:
The Given sequence is : 1,8,15,22,.....
As, difference of two consecutive terms is same,which is =7, so it is an arithmetic progression.
First term = a=1
Common difference(d) = Second term - first term = Third term - Second term
= 8 -1 or 15-8
= 7
nth term of the Sequence
= a + (n-1)× d
= 1 + (n-1)× 7
= 1 + 7 n - 7
= 7 n -6

Answer:
T and F
Step-by-step explanation:
Hi! Maybe I am reading it wrong, but only 2 statements are given. The answer to these statements are true and false.
"A square root of 16 is 4."
4 squared, or 4 * 4 is equal to 16, and therefore this is true.
"The only square root of 9 is -3."
This is false. 9 has 2 square roots: 3 and -3.
3 * 3 = 9, and so does (-3) * (-3).
So we have T and F, which eliminates the second, third, and fourth choices, which means even without a last statement, A is your correct answer.
Hope I helped! :)
