Considering A to Z values as 1 to 26. A and B's sum of associated values is 3 . multiply 3 by 2 yields 6. Same way C and D's sum of associated values is 7 , when multiplied by 2 yields 14 . And N is the 14th positioned letter in the A to Z series . Same way E and F's sum of associated value is 11 , when multiplied by 2 yields 22 and 22nd positioned letter in A through Z series is V .
