What should come in place of the question mark (?) in the given series? 6, 10, 18, 30, 46, ?
66
Look at the differences between consecutive terms: 10 − 6 = 4, 18 − 10 = 8, 30 − 18 = 12, 46 − 30 = 16.
The differences themselves increase by 4 each time: 4, 8, 12, 16, so the next difference is 16 + 4 = 20.
Add this to the last term: 46 + 20 = 66.
Hence, the number that should come in place of the question mark is 66.
