The 20th term of the sequence is 62.

The given sequence;

a_n = 5 + 3 (n-1)

A sequence is a set of numbers that increases or decrease in a particular order.

  • To determine the nth term of a sequence it is important to understand the definition of the given sequence.
  • Then substitute accordingly the value of the nth term and simply to obtain the required sequence.

The 20th term of the sequence is calculated as follows;

a_{20} = 5 + 3(20 -1)\\\\a_2_0 = 5+ 3(19)\\\\a_{20} = 62

Thus, the 20th term of the sequence is 62.

vladimir1956 [14]

Answer:

Step-by-step explanation:

Let us assume that if possible in the group of 101, each had a different number of friends.  Then the no of friends 101 persons have 0,1,2,....100 only since number of friends are integers and non negative.

Say P has 100 friends then P has all other persons as friends.  In this case, there cannot be any one who has 0 friend.  So a contradiction.  Hence proved

Part ii: EVen if instead of 101, say n people are there same proof follows as

if different number of friends then they would be 0,1,2...n-1

If one person has n-1 friends then there cannot be any one who does not have any friend.

Thus same proof follows.

Lady bird [3.3K]

Answer:

A

Step-by-step explanation:

The expected profit would be the sum of all the possibility multiplied. It means,

<em>"We need to multiply the profit by its possibility and add it with the product of the loss and its possibility."</em>

<em />

This will be the expectation, or expected profit.

Let's do it:

Expected Profit = (26,000)(0.7) + (-8000)(0.3) = 15,800

The correct answer is A
