Prove it by induction on n, use 0 or 1 as base cases.
The nth term is 22n and so the next number will be 5*22 = 110
28 - 8n
The exponential expression a^n is read a to the nth power. In this expression, a is the base and n is the exponent. The number represented by a^n is called the nth power of a.When n is a positive integer, you can interpret a^n as a^n = a x a x ... x a (n factors).
