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

you get

[tex]x_n = 2+5(n-1) [/tex]

Hey there,

                                       Your question states: 

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

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

The [tex]mean[/tex] of the arithmetic sequence would be [tex]\boxed{12}[/tex]

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

[tex] \boxed{a_{n} =5n-3}[/tex]

Hope this helps.
