1

a.-7.84
b.-8.16
c.-7.8
d.-58

Answer 1

Sum of an Infinite Geometric Sequence is given by:

\[\large Sum = \frac{a}{r-1}\]

Here a = -8 and r = -0.02..

Plug in the values and find the Sum..

Answer 2

ok got it,it was 7.84 thank you !

Answer 3

\[Sum = \frac{-8}{-0.02 - 1} = \frac{8}{1.02} = 7.84\]

Yes you are right..
