What is the next number in this sequence?

Explanation

The next number in the series is always found by adding the previous number to the number before it. So you calculate the number at position 3 by adding the number at position 2 to the number at position 1.
210 + 14 = 224
224 + 210 = 434
434 + 224 = 658
658 + 434 = 1092
1092 + 658 = 1750
1750 + 1092 = 2842
