Question

What is the explicit formula for this sequence? -5, - 3, -1, 1, 3, ...

Answer 1

Answer:

$a_n = -5 +(n-1)*2$

Step-by-step explanation:

Step 1:  Determine the variables

Initial number is -5

Increments of +2

Step 2:  Create an explicit formula

$a_n = initial+(n-1)*increment$

$a_n = -5 +(n-1)*2$

Answer: $a_n = -5 +(n-1)*2$
