Question

I need help to solve this problem. Please and thank you!

Answer 1

Solution given:

`S_n=?`

`a_1=0.11`

`a_5=895.956875`

r=9.5

no of term(n)=5

we have

`S_n=(last \:term *r-a)/(r-1)`

`S_5=(a_5*r-a)/(r-1)`

`S_5=(895.956875*9.5-0.11)/(9.5-1)`

`S_5=(8511.480313)/(8.5)`

`S_5=1001.35`

Option 1st is a required answer.
