Select the letter number cluster that can replace the question mark [?] in the following series.

E V 10, H S 16, M N 26, ?, C X 58

  • A.T H 40
  • B.T G 36
  • C.S G 36
  • D.T G 40

Answer: D

The missing cluster is T G 40.

First letters: E (5), H (8), M (13), ?, C. The gaps are +3, +5, +7, +9, so the missing letter is \(13 + 7 = 20\), T, and then \(20 + 9 = 29\), which wraps round to 3, C, as given.

Second letters are the opposites of the first (letters whose positions add to 27): E-V, H-S, M-N, so T pairs with G. Numbers are twice the first letter's position: 10, 16, 26, so T gives 40, and C (29 on the wrap) gives 58, as given.

T H and S G break the letter rule, and 36 breaks the number rule.
