What type of sequence has a constant term added to each term to generate the next term?

we know that

In an Arithmetic Sequence the difference between one term and the next is a constant

The constant term added to each term to generate the next term is called common difference

We can write an Arithmetic Sequence as a rule:

xn = a1 + d(n−1)

where

a1 is the first term

d is the "common difference" between terms

n is the numbers of terms

therefore

the answer is

Arithmetic Sequence

answer4 to the second power is 16

and 4 to the third power is 64,
