Answer 2

Let's observe the sequence.
First term is 1, second is 3. Difference is 2.
Second is 3, third is 5, Difference is 2.
Third is 5, fourth is 6, Difference is 1.
Fourth is 6, fifth is 8, Difference is 2.
Fifth is 8, sixth is 10, Difference is 2.
Sixth is 10, seventh is 11. Difference is 1.
So,differences are coming in order 2,2,1.
So, seventh is 11, eight is 13, difference is 2.
So next difference must be 2. Which means,
Ninth - eighth = 2, so ninth - 13 = 2, so ? Is 15. As we can see, next term is 16, so difference is 1 and series continues.
