- The series seems to be decreasing as you move from left to right.

- Calculate the difference between consecutive terms to identify the pattern:

- 2168 to 1979: decrease of 189

- 1979 to 1790: decrease of 189

- 1790 to 1601: decrease of 189

- 1601 to 1412: decrease of 189

- The pattern shows a consistent decrease of 189.

- From 1412, subtract 189 to find the missing number.

- 1412 - 189 = 1223

- Option 1: 1223 fits the pattern.

Given the explanation, your choice:

- Option 1: 1223 is indeed correct.
