Given series: 3,4,6,7,9,10
We note:
4 is the previous term 3 increased by 1,
6 is the previous term d increased by 2,
7 is the previous term 6 increased by 1,
9 is the previous term 7 increased by 2,
10 is the previous term 9 increased by 1
We note that a term is alternately the previous term increased by 1 or increased by 2.
Since we increased by 1 to obtain the last term, we then expect the next term to be the last term 10 increased by 2 which results in 12.
10+2=12
