Answer:
arithmetic sequence where each term increases by 2 with respect to the previous term. Starting from the first term, which is 1, we add 2 repeatedly to get the following terms:
1 + 2 = 3
3 + 2 = 5
5 + 2 = 7
7+2=9
So the next three terms in the sequence would be:
9+2=11
11 + 2 = 13
13 + 2 = 15
next three terms are 11, 13, 15
