40, 36, 33, 31, ?
Examine the differences between consecutive numbers in the series: 40, 36, 33, 31.
$40 - 36 = 4$
$36 - 33 = 3$
$33 - 31 = 2$
The differences are 4, 3, and 2. This shows a pattern where the difference decreases by 1 at each step.
Following the identified pattern, the next difference should decrease by 1 again, becoming 1.
To find the missing number, subtract this next difference (1) from the last number in the series (31):
$31 - 1 = 30$
Therefore, the number that replaces the question mark is 30.
Select the number from among the given options that can replace the question mark (?) in the following series.
