Question

Which number will replace the question mark (?) in the following series? 2, 7, 14, 23, ?, 47

Accepted Answer

Correct answer: D — Find the differences between consecutive terms of the series: 7 − 2 = 5 14 − 7 = 7 23 − 14 = 9 ? − 23 = 11 → ? = 23 + 11 = 34 47 − 34 = 13 The differences are consecutive odd numbers: +5, +7, +9, +11, +13. Adding 11 to 23 gives the missing term, 34.
