Question

Evaluate the following sum of the infinite series by recognizing it as either a transformation of a Taylor series or a Taylor series. 

The image shows an infinite series:

\[
\frac{7}{13} - \frac{7^3}{13^3 \cdot 3} + \frac{7^5}{13^5 \cdot 5} - \frac{7^7}{13^7 \cdot 7} + \cdots = 
\]

This series involves alternating positive and negative terms with increasing odd powers of 7 in both the numerator and the denominator, coupled with odd integers. The pattern suggests the use of a generating function or series expansion, possibly related to trigonometric functions or logarithms.
