The number of letters b/w
A and F is 4
F and O is 8
O and B is 12
B and S is 16
now,
The no. of letters between S and ? should be 20
hence,
The number of letters b/w
S and N is 20.
so,N will be the next letter of the sequence.

Pranaya   11 years AGO

gap between two character (excluding charatcer) becomes 4n, therefore it becomes series like
A->F=4;
F->O=8;
O->B=12;
B->S=16;
(4,8,12,16)
S->N=20.
hence next character must be N.

somya kulshrestha   11 years AGO

A,F,O,B,S,.....
alphabets occur in a multiple of 4 i.e. F after 4 alphabets and O after 8 alphabets and B after 12 and S after 16 thus they follow a pattern of 1,4,8,12,16,20,.... thus next letter after S is N.

Difference between the adjacent alphabets is as.
4,8,12,16,20

Hence after S skipping 20 alphabets
=> N
Therefore 6th option is correct
