5-87.

Write the first five terms of of each recursively-defined sequence. Homework Help ✎

1. t(1) = −3
t(n + 1) = −2 · t(n)

2. t(1) = 8
t(n + 1) = t(n) − 5

3. t(1) = 2
t(n + 1) = (t(n))−1

−3, 6, −12, 24, −48

Substitute 8 for t(n) in the second equation to find
t(n + 1), which is t(2).
t(2) = (8) − 5
t(2) = 3

8, 3, −2, −7, −12

$2, \frac{1}{2}, 2, \frac{1}{2}, 2$
