Find the sum of the GP :
1 +
+ 3 + 3
+….. to 10 terms
Sum of a G.P. series is represented by the formula,
, when r>1. ‘Sn’ represents the sum of the G.P. series upto nth terms, ‘a’ represents the first term, ‘r’ represents the common ratio and ‘n’ represents the number of terms.
Here,
a = 1
r = (ratio between the n term and n-1 term)
÷ 1 =
= 1.732
n = 10 terms
