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

$S_n=\frac{last \:term *r-a}{r-1}$

$S_5=\frac{a_5*r-a}{r-1}$

$S_5=\frac{895.956875*9.5-0.11}{9.5-1}$

$S_5=\frac{8511.480313}{8.5}$

$S_5=1001.35$

Option 1st is a required answer.
