Question

Describe the following sequence as arithmetic, geometric, nelther, or both.

2, 4, 6, 12, 14....
O both
O arithmetic
O geometric
O neither

Answer 1

It is an arithmetic sequence or progression.

Explanation:

2, 4, 6, 12, 14, …

2 is the first term

4 is the second term

let's get the common difference, d :

`d = a_(2) - a_(1) \\ d = 4 - 2 \\ d = 2`

since common difference is the same through out, it is an arithmetic progression.
