Got 102.5 and i checked my work multiple times (exterior)

Use the function nest to evaluate p(x) = 1 + x + · · · + x50 at x = 1.00001. (use the matlab ones command to save typing.) find the error of the computation by comparing with the equivalent expression q(x) = (x51 − 1)/(x − 1).

What is the prime factorization of 195

What is the value of f(x) = 2.2 for f(-2)?
