2, 4, 6, 8, 10, … What number should come next?

11

The answer is 12.

This is an arithmetic sequence with a common difference of 2. This means that each term is 2 more than the term before it. So, the next number in the sequence is 10 + 2 = 12.

Option A is incorrect because 11 is not in the sequence.

Option B is correct because 12 is in the sequence.

Option C is incorrect because 13 is not in the sequence.

Option D is incorrect because 14 is not in the sequence.
