5-87.

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

1. $t(1)=-3$
$t(n+1)=-2·t(n)$

• −3, 6, −12, 24, −48

1. $t(1)=8$
$t(n+1)=t(n)-5$

• 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

1. $t(1)=2$
$t(n+1)=(t(n))^{-1}$

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