Find the one which does not belong to that group ?
Correct answer: C. 608
- A. 508
- B. 328
- C. 608
- D. 148
Explanation
The digit sums are 5 + 0 + 8 = 13, 3 + 2 + 8 = 13, 6 + 0 + 8 = 14, and 1 + 4 + 8 = 13. Therefore, 608 is the only number whose digits do not add to 13. A student may choose 328 by overlooking that its digits also sum to 13.

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.
