Find the sum of the series.

Answer:
as per my point to view you can use a L.C.M so you can get the answer or you can try using a exponent way like 5by 1 as n value is 1 so it may give yoh answer
Answer:
1/12
Step-by-step explanation:
firstly the answer will not be -,because 5^(-n)>7^(-n)
then we try the value for first 2:(2/35)+(24/1225)=94/1225
then we can know for n=<3 the value outcome is too small
and 12×94/1225=1128/1225 and the value is nearly 1/12 and that is the answer.
or need limits to do
