Find the sum of the geometric series. 8-2+1/2-1/8+

a.) 220/7
b.)286/13
c.)66
d.)32/5

D.) 32/5

Step-by-step explanation:

As this geometric series is an infinte series , The Sum of this series can be determined with the help of the formula written below.

where,

S = Sum of the geometric series

a = First term of the geometric series = 8

r = The common ratio between the terms =

Now,

By substituting the values in the above formula we get,

                =

the answer is 5636.7

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
