B D G

D O K

T A P

K C ?

Which letter replaces the question mark?

[Guest]

This is the first thing I thought of...

O

I'm not that great at explaining, but here goes.

You count the # of letters between the given letters for the pattern, starting again at A when you reach Z

First Row:There's 1 letter between B and D, and 2 letters between D and G.

Second Row: There's 10 letters between D and O, and 21 letters between O and K.

Third Row: There's 6 letters between T and A, and 14 letters between A and P.

So, the pattern is

# letters between 2nd 2= 2(# of letters between 1st 2)+(row#-1).

For row four, then, we get:

# letters between 2nd two=2(17)+(4-1)

#letters between 2nd two=34+3=37

Which, by my count, gives you O.

I think?

It's not O...

Try guessing again....

The answer should be 'V'.... If we go in cyclic order the exact sequence is: B D G K P ?(V) C K T D O A..... the difference between two consecutive letters are increasing by 1.
