What should come in place of ‘?’ in the given series? 15 24 31 40 47 56 ?
63
Find the differences between consecutive terms: 24 – 15 = 9, 31 – 24 = 7, 40 – 31 = 9, 47 – 40 = 7, 56 – 47 = 9.
So the differences alternate between +9 and +7. The last difference used was +9, so the next one is +7.
Therefore the missing term = 56 + 7 = 63.
Check: the full series is 15, 24, 31, 40, 47, 56, 63 with differences 9, 7, 9, 7, 9, 7, which keeps the alternating pattern unbroken.
Hence, 63.
