Analyze the sequence below and identify the term that does not match the established pattern:

2, 40, 87, 144, 211, 288, 375

The correct option is 2.

To identify the number that does not match the established pattern, let us analyze the differences between consecutive terms in the given sequence:

Given sequence: 2, 40, 87, 144, 211, 288, 375

Let us calculate the differences between adjacent terms starting from the second term:

$375-288=87$

$288-211=77$

$211-144=67$

$144-87=57$

$87-40=47$

We can clearly see a pattern in the differences between consecutive terms: 47, 57, 67, 77, 87. The differences are increasing by 10 at each step.

Following this established pattern backwards, the difference between the second term (40) and the first term should be:

$47-10=37$

Therefore, the first term should be:

$40-37=3$

Since the sequence has 2 instead of 3 as its first term, 2 is the term that does not match the established pattern.
