Find the sum to the indicated number of terms in the geometric progression: $x^{3}, x^{5}, x^{7}, \ldots$ for $n$ terms (where $x \neq \pm 1$).

• A
  $\frac{x^{3}(1-x^{2n})}{1-x^{2}}$
• B
  $\frac{x^{3}(1-x^{n})}{1-x^{2}}$
• C
  $\frac{x^{2}(1-x^{2n})}{1-x^{2}}$
• D
  $\frac{x^{3}(1-x^{2n})}{1-x}$
