Find the next terms of the following series.

A99,223

B123,210

C120,185

D99,123

E99,185

| | | Asked In IBM |

Explanation:

Arrange the series as below
(33,8,41),(46,21,67),(72,47,119),(124,?,?)
For each group:
33 - 8 = 25
33 + 8 = 41
Similarly for other groups
46 - 21 = 25
46 + 21 = 67
so for next occurrence
124 - 25 = 99
124 + 99 = 223
