Answer:
the correct answers are 22 and 8
Answer:
Step-by-step explanation:
To prove that
is a multiple of 7.
Proof by induction:
Let n =1. Then we have 8-1 =7 is a multiple of 7
Thus the P(1) is true.
Let us assume that P(n) is true.
= 7l is true for some integer l
To check for P(n+1)
=LHS
=![8^n(8)-1\\=(7l+1)8-1\\=56l+7\\=7(8l+1)](https://tex.z-dn.net/?f=8%5En%288%29-1%5C%5C%3D%287l%2B1%298-1%5C%5C%3D56l%2B7%5C%5C%3D7%288l%2B1%29)
Thus we find that this is also a multiple of 7.
If true for n, then true for n+1
Hence we find that since true for 1, we have it is true for all natural numbers.
