What are the missing letters in this pattern?
Take the numbers corresponding to letters of the alphabet, that is a=1, b=2,….z=26, and convert these letters into numbers. For example, the first set would be 38, 2515 and 112. If you write these numbers one below the other for each line, and add the column-wise numbers, you would get the totals as 4432, 3114 and 4195 respectively. The second and third column totals differ from the first column total by 1318 and 237 respectively. Converting these back to alphabets (13=M, 18=R, 23=W and 7=G), the missing alphabets to follow YO in the last line would be MR and WG respectively.
