Let's complete the sequences by identifying the missing numbers. Each sequence increases by 1, so we will continue this pattern.
210, 211, 212, 213 , 214 The sequence increases by 1 each time, so the missing number is 213.
248, 249, 250 , 251, 252 The sequence increases by 1 each time, so the missing number is 250.
267, 268, 269, 270, 271 The sequence increases by 1 each time, so the missing number is 271.
286, 287 , 288, 289, 290 The sequence increases by 1 each time, so the missing number is 287.
295, 296, 297 , 298, 299, 300 The sequence increases by 1 each time, so the missing numbers are 297 and 300.
