A5=2500 and a8=312,500 in explicit form geometric sequence and series

If is a geometric sequence, then there is some for which

We have

so

Then

So this sequence is recursively defined by

and explicitly by

answer: y=4000x+14000

step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
