Identify the number that should replace the question mark (?) in the sequence given below to complete the pattern.

120, 208, 286, ?, 412, 460

The correct answer is 354.

To find the missing number in the sequence, let us analyze the differences between consecutive terms:

1^st difference: 208 - 120 = 88

2^nd difference: 286 - 208 = 78

Notice the pattern in the differences: each successive difference decreases by 10.

Following this pattern, the next difference should be:

3^rd difference: 78 - 10 = 68

Now, add this difference to the term preceding the question mark (286):

$286+68=354$

Let us verify the remaining terms using the same decreasing difference pattern:

4^th difference: 68 - 10 = 58

Check next term: 354 + 58 = 412 (Matches the given sequence)

5^th difference: 58 - 10 = 48

Check final term: 412 + 48 = 460 (Matches the given sequence)

Thus, the number that replaces the question mark (?) is 354.
