NIMCET | Reasoning | 2023Complete the series: 3, 10, 24, 45, 73, ......
Choose the correct answer:
- A.
69
- B.
91
- C.
108
(Correct Answer) - D.
121
108
Explanation
Step-by-step Solution
1. The differences between consecutive terms in the given series are calculated:
• The difference between the second term and the first term is 10−3=7.
• The difference between the third term and the second term is 24−10=14.
• The difference between the fourth term and the third term is 45−24=21.
• The difference between the fifth term and the fourth term is 73−45=28.
2. A pattern is observed in these differences: 7,14,21,28. It is noted that each subsequent difference is greater than the previous one by 7. This indicates an arithmetic progression of differences with a common difference of 7.
3. To find the next term in the series, the next difference in the pattern is determined. Following the established pattern, the next difference after 28 should be 28+7=35.
4. This calculated difference is added to the last known term in the series to find the missing term: 73+35=108. [1]
Final Answer
The next number in the series is 108.
