Download the Arithmetic Odd Man Out and Series Concept and MCQs with Free PDF for PPSC, FPSC, PMS, NTS, KPKPSC, and SPSC exam
- Arithmetic Odd Man Out is a type of question that asks you to find the number that does not belong in a sequence. The sequence may be arithmetic, geometric, or some other type of progression. To solve an arithmetic odd-man-out question, you need to identify the rule that governs the sequence and then find the number that does not follow the rule.
- Arithmetic Series is a sequence of numbers where the difference between any two consecutive terms is constant. This constant difference is called the common difference.
Here are some examples of arithmetic odd-man-out questions:
- 1, 3, 5, 7, 9, 12
- 2, 4, 8, 16, 32, 65
- 10, 15, 20, 25, 30, 40
The answer to the first question is 12. This is because the first four numbers are all odd numbers, but 12 is an even number. The answer to the second question is 65. This is because the first four numbers are all powers of 2, but 65 is a power of 4. The answer to the third question is 40. This is because the first four numbers are all multiples of 5, but 40 is not a multiple of 5.
Here are some examples of arithmetic series:
- 2, 4, 6, 8, 10, 12
- 5, 10, 15, 20, 25, 30
- 1, 4, 9, 16, 25, 36
The common difference in the first series is 2, the common difference in the second series is 5, and the common difference in the third series is 3.
