ArithmeticNumber Series & Progressions
24576, 6144, 1536, 386, 96, 24. Find the odd number of the above series.
  1. a.96
  2. b.386
  3. c.1536
  4. d.6144

Answer: (B) 386

Each term is the previous one divided by 4: 24576 ÷ 4 = 6144, 6144 ÷ 4 = 1536, and 1536 ÷ 4 = 384, not 386. Then 384 ÷ 4 = 96 and 96 ÷ 4 = 24 fit, so 386 is the odd number.
