283

190

- Let's examine the series: 177, 190, 205, 224, 249, 283.

- Calculate the differences:

- 190 - 177 = 13

- 205 - 190 = 15

- 224 - 205 = 19

- 249 - 224 = 25

- 283 - 249 = 34

- Notice that differences should be in a recognizable pattern.

- They actually increase following the sequence: 13, 15, 19, 25, 31 (not 34).

- This sequence should add the next odd number increment.

- 283 seems incorrect, as the expected number should be 249 + 31 = 280.

Option 4, 283 is the wrong number.
