a n = 2 n + 1
Since in a geometric sequence each term after the first is found by multiplying the previous one by a fixed, non-zero number, thus we have to get that number by dividing nth term by the previous term.
We can say a sequence is geometric if and only if all of the division answers are fixed and constant.
5 3 7 5 so your sequence is not geometric.
