What comes next in the following series: 64, 48, 40, 36, 34, …?

  • (A) 30
  • (B) 31
  • (C) 32
  • (D) 33
  • Solution: Let's look at the pattern of the difference between two consecutive numbers:
  • 64 to 48 is -16
  • 48 to 40 is -8
  • 40 to 36 is -4
  • 36 to 34 is -2
  • Each difference is half the difference before:
  • -16, -8, -4, -2, -1
  • So the next difference should be: -1
  • Which is: 34 - 1 = 33
