Find the one which does not belong to that group ?
Correct answer: A. 35
- A. 35
- B. 48
- C. 75
- D. 84
Explanation
48, 75, and 84 are divisible by 3 because their digit sums are 12, 12, and 12 respectively. The digit sum of 35 is 3 + 5 = 8, so it is not divisible by 3. A student may choose 48 because it is the only number below 50 that is even, but parity is not the shared property.

About Sequences and Series
Sequences describe ordered terms formed by a pattern, while series represent the sum of those terms. Questions cover arithmetic and geometric sequences, their nth terms, common difference or ratio, finite sums, and applications, with the sequence itself kept distinct from the corresponding series.
