Question

Help please.
Prove that for every n >= 1, the number 11^n+1 + 12^2n-1 is divisible by 133.

Answer 1

i'd probably say use mathematical induction

Answer 2

n=1\[11^{n+1} + 12^{2n-1}=11^2+12=133\]its true for n=1

Answer 3

now suppose the statement holds for n, prove it holds for n+1

Answer 4

are u familiar with mathematical induction?

Answer 5

i got it now thanks.

Answer 6
