The missing term in the series2, 7, 24, 77, ?, 723 is1. 2382. 4323. 5424. 320

Answer» Correct Answer - Option 1 : 238

Calculation

The series is 2, 7, 24, 77, ?, 723

Its terms can be written as :

2 × 3 + 1 = 7

7 × 3 + 3 = 24

24 × 3 + 5 = 77

So, the next term will be

77 × 3 + 7 = 238

And last term is

238 × 3 + 9 = 723

∴ The required term is 238
