For this case we have the following arithmetic sequence:

a_ {n} = 15 + 5 (n-1)

To write in function form, we apply distributive property to the terms within parentheses:

f (n) = 15 + 5n-5

Different signs are subtracted and the major sign is placed.

We simplify:

f (n) = 5n + 10

Answer:

f (n) = 5n + 10
