Given : Mr Singh has saved 5000 this year . Next year he plans to save double amount he has saved this year . He plans to continue saving in this manner for next four years. To find : the total amount he will save at the end of fifth year Solution: Saving on 1st year = 5000 Saving on 2nd year = 5000 x 2 = 10000 Saving on 3rd year = 10000 x 2 = 20000 Saving on 4th year = 20000 x 2 = 40000 Saving on 5th year = 40000 x 2 = 80000 Total Saving = 5000 + 10000 + 20000 + 40000 + 80000 =155000 Using GP a = 5000 , r = 2 , n = 5 Sₙ = a(rⁿ – 1)/(r – 1) = 5000 ( 2⁵ – 1) /(2 – 1) = 5000 ( 32 – 1)/ 1 = 5000 ( 31) = 155000 Rs Learn more: In an infinite g.P.

Given : Mr Singh has saved 5000 this year .
Next year he plans to save double amount he has saved this year .
He plans to continue saving in this manner for next four years.
To find : the total amount he will save at the end of fifth year
Solution:
Saving on 1st year = 5000
Saving on 2nd year = 5000 x 2 = 10000
Saving on 3rd year = 10000 x 2 = 20000
Saving on 4th year = 20000 x 2 = 40000
Saving on 5th year = 40000 x 2 = 80000
Total Saving = 5000 + 10000 + 20000 + 40000 + 80000
=155000
Using GP
a = 5000 , r = 2 , n = 5
Sₙ = a(rⁿ – 1)/(r – 1)
= 5000 ( 2⁵ – 1) /(2 – 1)
= 5000 ( 32 – 1)/ 1
= 5000 ( 31)
= 155000 Rs
