29, 31, 37, 49, 69, ?

Solution
+The difference between the consecutive terms is:

31-29 = 2

37 -31 = 6

49- 37 = 12

69-49 = 20

Here, the difference between the consecutive difference terms is

6-2 = 4

12-6 = 6

20-12 = 8

Hence, the next term in difference series = 10

Therefore the next term in series = 69+30 = 99
