Let C(n) be the constant term in the expansion of (x + 6). Prove by induction that C(n) = 6 for all n E N. (Induction on n.) The constant term of (x + 6)¹ is Suppose as inductive hypothesis that the constant term of (x + 6)k-1 is Then (x + 6) = (x + 6)k-1. so its constant term is for some k> 1. 6 = as required.

asnwer the following boxes 

Let C(n) be the constant term in the expansion of (x + 6)". Prove by induction that C(n) = 6" for all n E N.
(Induction on n.) The constant term of (x + 6)¹ is
Suppose as inductive hypothesis that the constant term of (x + 6)k-1 is
Then (x + 6) = (x + 6)k −1 .
so its constant term is
for some k > 1.
.6=
, as required.
