Answer:
The sum of 10 terms G.P is 310.
Step-by-step explanation:
We are given the following in the question:
There are 10 terms in a geometric series.
First term, a = 3
Last term = 59
[tex]a_{10} = 59[/tex]
Sum of n terms of a geometric progression is given by:
[tex]S_n = \dfrac{n(a+a_n)}{2}[/tex]
Putting the values, we get,
[tex]S_{10} = \dfrac{10(3+59)}{2} = 310[/tex]
Thus, the sum of 10 terms G.P is 310.
