A geometric progression is a sequence of numbers in which each value (after the first) is obtained by multiplying the previous value in the sequence by a fixed value called the common ratio. for example the sequence 3, 12, 48, 192, ... is a geometric progression in which the common ratio is 4. given the positive integer ratio greater than 1, and the non-negative integer n, create a list consisting of the geometric progression of numbers between (and including) 1 and n with a common ratio of ratio. for example, if ratio is 2 and n is 8, the list would be [1, 2, 4, 8]. associate the list with the variable geom_prog.
