Question

Choose the group in which all numbers belong to the same category:

• A. 2,4,6,8
• B. 3,6,9,11
• C. 5,10,13,21
• D. 7,14,26,38

Answer 1

Answer:

A. 2,4,6,8

Let's check each group for a common property.

• A. 2, 4, 6, 8 → All are even numbers. ✅

• B. 3, 6, 9, 11 → 3, 9, and 11 are odd, but 6 is even.

• C. 5, 10, 13, 21 → Mix of prime, even, and odd numbers; no common property.

• D. 7, 14, 26, 38 → 7 is odd, while 14, 26, and 38 are even.

Therefore, the group in which all numbers belong to the same category is:

2, 4, 6, 8 (all are even numbers).
