Question

What is the function for the arithmetic sequence 2,7,12,17,22

Answer 1

Hey there,

Your question states:

What is the function for the arithmetic sequence
(2,7,12,17,22)

By using the formula
`[tex] a_(n) \ a_(1) + d(n-1) \ to \ get \ the \ sequence`

The
`mean` of the arithmetic sequence would be
`\boxed{12}`

And by identifying the sequence by using the formula, it would be . . .


`\boxed{a_(n) =5n-3}`

Hope this helps.

Answer 2

The common difference, d, is 5 and the starting value, a, is 2.
Filling this in the form of
`x_n=a+d(n-1)`

you get


`x_n = 2+5(n-1)`
