Question

Geometric series in context

Answer 1

For this case we can model the problem with a geometric series given by:

`a_n=600(1+0.2)^(n-1)`

And we can find the value for n=23 and we got:

`a_(23)=600(1.2)^(23-1)=33123.69`

And rounded to the neares whole number we got 33124

and using the sum formula we got:

`S_(23)=(600(1.2^(23)-1))/(1.2-1)=195742`
