a1=.375, ak+1=ak+.25

Answer 1

helpppppppppppp

Answer 2

Just add up:
a2 = a1 + .25
a3 = a2 + .25
a4 = a3 + .25
a5 = a4 + .25
That's the concept of arithmetic accumulation!

Answer 3

I have the first five terms. but how do i get the nth term of a sequence as a function?

Answer 4

You don't have the formula for n term?

Answer 5

nth term = 1st term + (n -1) d
