Question

sum of n terms of the series 0.5+0.55+0.555.....equals to?

Answer 1

The series given is in GP as:

0.55/0.5 = 1.1

0.555/0.55 = 1.1

r = 1.1

a = 0.5

Sum of GP for infinite series = a/(r - 1)

                                             =0.5/(1.1 - 1)

                                             =5
