Question

The sum to infinity of the GP -5/4, 5/16, -5/64...is​

Answer 1

Answer:

sum to infinity =a/(1-r). ; a= -5/4 ; r= -¼

=-5/4/(1--¼)

= -1

Answer 2

Answer:

1

Step-by-step explanation:

given G.P  -5/4,5/16,-5/64.........

here a=-5/4  , r=5/16/-5/4=-1/4

sum of infinity of a G.P=$\frac{a}{1-r}$

                                     =$\frac{\frac{-5}{4} }{1+\frac{1}{4} }$=1
