Find the next number in the series.2, 35, 104, 209

Answer: 350

Explanation: Find differences between consecutive terms and notice the pattern.

• 35 − 2 = 33

• 104 − 35 = 69

• 209 − 104 = 105

• The differences are 33, 69, 105; each difference increases by 36 (69 − 33 = 36, 105 − 69 = 36).

• Next difference = 105 + 36 = 141

• Next term = 209 + 141 = 350

Therefore the next number in the series is 350.
