B) 430
C) 439
D) 488

Answer 1

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 previous term-
11-7=4
27-11=16
91-27=64
Now series is 4,16,64,?
............
multiple with 4
4×4=16
16×4=64
hence
first multiple with 4 then add 91 and then add 141
64 ×4=256
256+91=347
347+141=488
