    Solution. I guess your question is to find the interval of the series with power function term. Is the general term as follows?

    Fn(x)=1/2*[(-1)^(n+1)*(x-2)^n]
    I answer your question if Fn(x) is of the form above.

    The series F1(x)+F2(x)+...+Fn(x)+...
    =1/2*(x-2)-1/2*(x-2)^2+...+1/2*(-1)^(n+1)*(x-2)^n+...

    ...

    Solution Summary

    An interval of convergence is found.
