ah, so an aritmetic sequence can be written in form

a_n=a_1+d(n-1)

where a_n is the nth term

a_1 is the first term

d is the common difference or how many times it increase or decreases each day



so an example:

Bob swims 2 miles on one day. Every day, he increases his distance by 0.2 miles. If he continues this pattern, how many miles will he swim on the 7th day?

a_n=a_1+d(n-1)

a_7=2+0.2(7-1)

a_7=2+0.2(6)

a_7=2+1.2

a_7=3.2

bob swims 3.2 miles on the 7th term

also, you can use f(n) instead of a_n
