The next number of the sequence 1, 4, 14, 45, 139, ...... is1. 4202. 3223. 4224. None of the above

Answer» Correct Answer - Option 3 : 422

Calculation

1, 4, 14, 45, 139, .....

These terms can be written as :

4 = (1 × 3) + 1

14 = (4 × 3) + 2

45 = (14 × 3) + 3

139 = (45 × 3) + 4

∴ The next term will be

(139 × 3) + 5 = 422
