29, 31, 37, 49, 69, ?
1). 108
2). 99
3). 94
4). 103
+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
