General Intelligence Number Series Number Series Question #6522 (CAT-I)

Identify the incorrect number in the series: 380, 188, 92, 48, 20, 8, 2

A 92

B 48

C 20

D 188

Correct Answer & Explanation

Option B

• The recurring pattern from one term to the next is (÷ 2 - 2). 380 ÷ 2 - 2 = 190 - 2 = 188 188 ÷ 2 - 2 = 94 - 2 = 92 92 ÷ 2 - 2 = 46 - 2 = 44 44 ÷ 2 - 2 = 22 - 2 = 20 20 ÷ 2 - 2 = 10 - 2 = 8 8 ÷ 2 - 2 = 4 - 2 = 2 • Thus, 48 is the wrong term; it should be 44.
