Explanation:

Alright, let's look at the sequence: 120, 128, 144, 168, ?, 240

- First, check the difference between terms:

- 128 - 120 = 8

- 144 - 128 = 16

- 168 - 144 = 24

- So, the differences are: 8, 16, 24.

- Looks like the difference increases by 8 each time.

- Following the pattern, the next difference should be 32 (24 + 8).

- Add 32 to 168:

- 168 + 32 = 200

- Then 240 - 200 = 40 (difference increases by another 8, so pattern stays consistent).

Options:

- 1) 216 — this would break the pattern.

- 2) 202 — doesn't fit the +8 growth.

- 3) 208 — also doesn’t keep the sequence.

- 4) 200 — fits the pattern perfectly.

So, 200 is the answer.
