What should come in place of the question mark (?) in the following number series? 300, ?, 148, 221, 441, 1101.5
- 115.5
- 150.5
- 149
- 51
Correct answer: 149
Solution
The series follows a pattern of alternating operations that leads to the missing term as 149. Once 149 is placed, the subsequent terms fit the intended progression. Such questions typically require identifying the hidden arithmetic pattern across consecutive terms.
