Question

12,37,43,92,100,? 3,8,24,48,?,168 5824,5242,?,4247,3823

Answer 1

For the first series,
it includes two series of numbers,
37-12=25=5²
43-37=6
92-43=49=7²
100-92=8
181-100=81=9²
∴, the required no. is 181
For the 2nd series:
the scheme is - (prime no)²-1
i.e., 2²-1=3
3²-1=8
5²-1=24
7²-1=48
11²-1=120
13²-1=168
∴, the required no. is 120
For the 3rd series:
the scheme is -  (the given no)-(no. formed by first 3 digits of the given no.)
5824-582=5242
5242-524=4718
4718-471=4247
4247-424=3823
∴, the required no. is 4718
