Explanation:

- Let's break down the series: 602, 598, 591, 563, 498, 372, 155.

- Check the pattern:

- 602 to 598: -4

- 598 to 591: -7

- 591 to 563: -28

- 563 to 498: -65

- 498 to 372: -126

- 372 to 155: -217

- At first, the series of differences is: 4, 7, 28, 65, 126, 217. These don't follow any recognizable mathematical pattern.

- Option breakdown:

- Option 1: 155 — Not obviously wrong based on differences.

- Option 2: 592 — Not even present in the list.

- Option 3: 598 — Present in list.

- Option 4: 598 — Same as above.

- Option 5: 372 — Seems to fit the difference pattern.

- Checking the pattern further, note the leaps are not consistent. However, upon reviewing, 598 appears to disrupt the gradual increase in difference size (decrement sequence irregular).

- So, option 4: 598 is the most likely wrong term.

Option:4, 598 is the correct answer.
