Solution :-
If we look at the series, the difference between the 1st number and 2nd number is 14 and this difference is increasing by 7 with every number in this series.
⇒ 289 + 14 = 303
⇒ 303 + 21 = 324
⇒ 324 + 28 = 352
⇒ 352 + 35 = 387
⇒ 387 + 42 = 429
⇒ 429 + 49 = 478
So, the required number is 478.
