Question

What is the eighth term in the arithmetic sequence defined by the explicit formula an=2n+7? Enter your answer in the box.

Answer 1

The 8th term is 23

Explanation:

If we are given the formula for the sequence

an=2n+7,

then to find the 8th term we substitute n=8 into the formula.

a8 = 2(8) +7

a8 = 16+7

a8 = 23

The 8th term is 23
