Question

12,14,18,26,38,62,.......... what is next term in this series?

Answer 1

Hint:
List the first difference between the terms, then the second difference (i.e. difference between the first differences).
You will see something interesting.

Answer 2

multiply n add
1*2 =2 so 12+2 =14
1*4 = 4 so 14+4=18
n so on
so 6*2 =12
so 62+12 =74

Answer 3

multiply by 2 so when you get to 64 you will see that you multiplied 12 by 2 to get 24 so 24*2=48, 62+48=110(next term)
