Lee has 3 dog walking customers. Each month he gains another customer. Which arithmetic sequence represents the number of customers he has? Group of answer choices

a1 = 3; an = an-1 + 1

a1 = 1; an = an-1 + 3

a1 = 1; an = an+1 + 3

a1 = 3; an = an+1 + 1

Given:

Lee has 3 dog walking customers.

Each month he gains another customer.

To find:

The arithmetic sequence that represents the number of customers he has.

Solution:

Initial number of customers = 3

First term :

Each month he gains another customer.

Common difference :

Recursive formula of an AP is

where, d is common difference.

Substituting d=1, we get

So, the required arithmetic sequence is , where .

Therefore, the correct option is A.

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4
