Given :
series = 5, 12, 23, 50, 141, ?
Finding the difference of the given sequence-
12 - 5 = 7
23 - 12 = 11
50 - 23 = 27
141 - 50 = 91
Now, series is 7, 11, 27, 91, ?
_______________________
Subtracting the previous term -
11 - 7 = 4
27 - 11 = 16
91 - 27 = 64
Now, series is 4, 16, 64, ?
_______________________
Multiplying with "4" -
4 x 4 = 16
16 x 4 = 64
Hence :
First multiply with "4" then add "91" and then add "141" -
64 x 4 = 256
256 + 91 = 347
347 + 141 = 488
The answer is 488.
