What should come in place of ‘?’ in the given series?
11, 22, 44, 88, 176, ?
352
To solve this numerical series question, we need to find the pattern or rule governing the sequence and then use it to determine the missing number. Let's examine the series provided:
- 11
- 22
- 44
- 88
- 176
- ?
Observe the progression from one number to the next:
- The second term (22) is double the first term (11): \(11 \times 2 = 22\)
- The third term (44) is double the second term (22): \(22 \times 2 = 44\)
- The fourth term (88) is double the third term (44): \(44 \times 2 = 88\)
- The fifth term (176) is double the fourth term (88): \(88 \times 2 = 176\)
Evidently, each term in the series is double the previous term. Therefore, to find the missing term after 176, we should simply double 176:
Calculate: \(176 \times 2 = 352\)
Thus, the number that should come in place of the question mark is 352.
We can now confidently conclude that the correct answer is:
352
