Answer:
Find out the what is the eighth term in the arithmetic sequence defined by the explicit formula.

To prove
As given the explicit formula for the arithmetic sequence .

Put n = 8



Therefore the eighth term in the arithmetic sequence is 23 .
20 - 7 = 13
8 - 13 = 5
13 + 5 = 18
20 - 18 = 2
So two is your answer because.....
13 + 5 + 2 = 20

Step-by-step explanation:
Let d represent number of dolls in 2nd basket.
We have been given that a day-care center has 2 baskets of dolls. One basket has 8 dolls, and the other basket has an unknown number of dolls in it. We are asked to represent this situation in an expression.
The number in both baskets would be equal to dolls in 1st basket plus dolls in 2nd basket.
We can represent this information in an expression as:
Therefore, our required expression would be
, where d represents number of dolls in 2nd basket.
