5. Find the next term
496, 492, 483, 467, ?

a. 442
b. 431
c. 462
d. 437

Answer: a. 442

Explanation:

496 - 492 = 4 = 22
492 - 483 = 9 = 32
483 - 467 = 16 = 42
So, the next has to be a difference of 25 = 52
467 - 25 = 442

  • Between O and L there are 2 alphabets.
  • Between L and H there are 3 alphabets.
  • Between H and E there are 2 alphabets.
  • Between E and A there are 3 alphabets.
  • So, between A and next letter there has to be 2 alphabets. So, it is X.
  • And between X and next letter there has to be 3 alphabets. So, it is T.
