Enter the first 5 terms of the sequence. f(1) = 45 and f(n) = f(n − 1) − 8 for each whole number n greater than 1. The first 5 terms are , , , , and .

Answer 1

f(n) = f(n - 1) - 8, f(1) = 45

We are looking at the arithmetic sequence with the common difference of -8.

f(2) = f(1) - 8 = 45 - 8 = 37

f(3) = f(2) - 8 = 37 - 8 = 29

f(4) = f(3) - 8 = 29 - 8 = 21

f(5) = f(4) - 8 = 21 - 8 = 13

The 5 terms in the sequence are 45, 37, 29, 21, and 13.
