Generate a column vector of the first $N$ series terms and assign this vector to the variable terms.

Generate a column vector of the first $N$ series summations. The first summation is $1,$ second is $1-\frac{x^2}{2}!,$ third is $1-\frac{x^2}{2}!+\frac{x^4}{4}!,$ and so on$.$ Assign this vector to the output variable seriesSums.
