General Intelligence Number Series Number Series Question #6555 (CAT-I)

Find the missing numbers in the given series: 1, 2, 3, 14, 5, 34, 7, ?, ?

A 68, 7
B 63, 9
C 60, 11
D 62, 9
Correct Answer & Explanation
Option D
• The given sequence is formed by combining two interleaved series: First series at odd positions: 1, 3, 5, 7, ? 1 + 2 = 3 3 + 2 = 5 5 + 2 = 7 7 + 2 = 9 • Second series at even positions: 2, 14, 34, ? 2² - 2 = 4 - 2 = 2 4² - 2 = 16 - 2 = 14 6² - 2 = 36 - 2 = 34 8² - 2 = 64 - 2 = 62 • Therefore, the missing numbers are 62 and 9 respectively.
