Question

Answer 1

Did you try it?

Answer 2

yes

Answer 3

So what happened :D , alright so n is the number of weeks. and the formula must be in terms of n

Answer 4

When n is 0 which is beginning of the 1 st week(that is week 0) , amount is 150

A(0) = 150

But what about week 1

A(1) = 1*25 + 150

and week 2

A(2) = 2*25 + 150

and so on

the formula is A(n) = 25*n + 150

Answer 5

okay
