Evaluate the series .
\(\dfrac{1}{3^1}+\dfrac{4}{3^2}+\dfrac{7}{3^3}+\dfrac{10}{3^4}+\cdots\)
+1072 Call this series S. We compare S to 1/3 S:
Subtracting the second equation from the first, we see that
Therefore,
+1072 I tried this answer and it is correct, one of the users above got the same answer as me
