Calculation:

23 - 14 = 9

34 - 23 = 11

47 - 34 = 13

The differences between consecutive terms are 9, 11, and 13. These are increasing by 2 each time.

The next difference should be 15 (since 13 + 2 = 15).

Now, add this difference to the last number in the series:

47 + 15 = 62

∴ The missing term in the series is 62.
