Which pair in the options will complete the following series:
A, _____, I, P, ____
- AD, Y
- BD, Z
- CE, Y
- DE, X
Solution & Step-by-step Explanation
Let's convert the letters into their alphabetical positional values:
*
*
*
Let's check the differences between positions assuming they match consecutive perfect squares or growing gaps:
* Let position 2 be ().
* Then gaps are:
*
*
*
The gaps between consecutive terms are consecutive odd numbers: .
* Next position = , which corresponds to .
Thus, the missing letters are D and Y.
