C Correct answer
Explanation

Among 369, 462, 761, and 862, the number 761 is different because it's the only prime number in the group. 369=3×123, 462=2×231, and 862=2×431 are all composite numbers. This makes 761 the odd one out.

Multiple choice

Directions: Choose the odd numeral pair/group in the following question.

  1. 4, 16, 24, 12

  2. 2, 8, 4, 16

  3. 1, 4, 2, 8

  4. 3, 12, 6, 24
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Looking at the sequences: B (2,8,4,16) follows ×4,÷2,×4. C (1,4,2,8) follows ×4,÷2,×4. D (3,12,6,24) follows ×4,÷2,×4. But A (4,16,24,12) follows ×4, then +8 (not ÷2), breaking the consistent pattern. This makes sequence A the odd one out.
