Question

Is this A??? help please.

Answer 1

A

Explanation:

It obviously multiplies by 2 each time since all the slopes are 2, so we are looking at the right n base here.

a_{1} = 2

a_{2} = 4

a_{3} = 8

and so on...

Plug in 2 for n and see if we get 4.

a_{2} = 2a_{2-1}

a_{2} = 2a_{1}

4 = 4

Since 2 * 2 = 4

A is correct
