5-108.

For each sequence defined recursively, write the first 5 terms and then define it explicitly.

$t(1)=12$
$t(n+1)=t(n)-5$
Hint (a):
Note t(1) is given.
Find: t(2)
t(1 + 1) = t(1) − 5
or t(2) = 12 − 5
ind: t(3):
t(2 + 1) = t(2) − 5
or t(3) = 7 − 5

$a_1=32$
$a_{n+1}=\frac{1}{2}a_n$
Hint (b):
See part (b) of problem 5-106.
