to different bases. The missing number in this sequence is
(A) 22
(B) 21
(C) 16
(D) 10
10000 covert in 2 base=16
121 covert in 3 base=16
100 covert in 4 base=16
31 covert in 5 base=16
24 covert in 6 base=16
22 covert in 2 base=16

If it's base
2= possible digits are 0,1
3=possible digits are 0,1,2 etc
So we can eleminate first 2 options.
(41)6=4*61+1*6=25
(121)4=1*42+2*4+1=25
Therefore, (D)4 is correct option
