Natural selection does not actually create mutations. It only acts upon already existing physical/genetic differences. Mutations also cannot be created in any fashion and arise spontaneously.

What is y, the second term in the geometric sequence 1/5, y, 1/405, 1/3,645?

y = 1/45. In a geometric series, the ratio of any term to its following term is constant, so we can find that ratio by dividing 1/3,645 by 1/405, then multiplying 1/5 by that ratio.
