Question
Direction:
What will come in place of the question mark (?) in the following number series?
83, 188, __, 374, 437, 452
Options:
- 280
- 239
- 487
- 445
- 287
Solution
The pattern in the series is as follows:
83, 188, __, 374, 437, 452
If we look at the differences between the numbers:
188 - 83 = 105 374 - 188 = 186 437 - 374 = 63 452 - 437 = 15
We can see that the differences are decreasing. If we look at the differences between these differences:
186 - 105 = 81 63 - 186 = -123 15 - 63 = -48
We can see that the differences between the differences are also decreasing. However, there is no clear pattern in these differences. Therefore, it is not possible to determine what number should come in place of the question mark based on the information given.
