Question

Create a formula to the sequence 2,8,14...

Answer 1

`a_n = 2+6(n-1)`

Explanation:

Explicit Arithmetic Formula:
`a_n=a_1 + d(n-1)`

a₁ is 1st term in sequence

d is common difference

n is term number

Step 1: Find d

d = 8 - 2 = 6

Step 2: Plug in variables into formula

`a_n = 2+6(n-1)`
