- This series alternates between adding and subtracting increasing numbers.

- The pattern likely follows additions and subtractions offset by varying values.

- Upon examining the sequence:

- 698 to 914: Increase by 216.

- 914 to 571: Decrease by 343.

- 571 to 1083: Increase by 512.

- 1083 to 357: Decrease by 726. (This step breaks the pattern significantly.)

- 357 to 1354: Increase by 997. (This step also confirms the break in pattern.)

- The sequence should have logical mathematical progressions, but here, the transitions seem inconsistent around 357.

- Hence, Option:5 - 357 breaks the expected pattern significantly.

- Answer: Option:5 - 357
