Verbal reasoning on letter series

Example 1:

Question:
What is the next letter in the series?
A, C, F, J, O, ___?

Solution:
The pattern is that the positions of the letters in the alphabet are increasing with the following difference:

  • A (1st letter)
  • C (3rd letter) → 1 + 2
  • F (6th letter) → 3 + 3
  • J (10th letter) → 6 + 4
  • O (15th letter) → 10 + 5

So, the next letter will be:
15 + 6 = 21, which is U.


Example 2:

Question:
What is the next letter in the series?
