(C) The general term of the series is $T_n = \frac{2n - 1}{(n - 1)!}$ for $n \geq 1$.We can rewrite the general term as:$T_n = \frac{2(n - 1) + 1}{(n - 1)!} = \frac{2(n - 1)}{(n - 1)!} + \frac{1}{(n - 1)!} = \frac{2}{(n - 2)!} + \frac{1}{(n - 1)!}$.The sum of the series is $\sum_{n=1}^{\infty} T_n = \sum_{n=1}^{\infty} \frac{2}{(n - 2)!} + \sum_{n=1}^{\infty} \frac{1}{(n - 1)!}$.Note that for $n=1$,$\frac{2}{(n-2)!}$ is defined as $0$ (since the factorial of a negative integer is infinite in the denominator).Thus,the sum is $2 \sum_{n=2}^{\infty} \frac{1}{(n - 2)!} + \sum_{n=1}^{\infty} \frac{1}{(n - 1)!} = 2e + e = 3e$.

$1 + \frac{3}{1!} + \frac{5}{2!} + \frac{7}{3!} + ....\infty = $
