Find the next element that replace the ? Logically 30, 41, 54, 69, ?
86
Here the terms increase by a growing amount, so we compute the differences between successive terms to spot the pattern.
First difference: \(41 - 30 = 11\).
Second difference: \(54 - 41 = 13\).
Third difference: \(69 - 54 = 15\).
The gaps 11, 13, 15 form their own sequence rising by 2, so the next gap is \(15 + 2 = 17\).
Add this to the final given term: \(69 + 17 = 86\).
Because the differences follow their own arithmetic pattern, this is a second-order series, and the required number is 86.

In the following question, four number pairs are given. In each pair the number on left side of (−) is related to the number of the right side of (−) with some Logic/Rule/Relation. Three pairs are similar on the basis of same Logic/Rule/Relation. Select the odd one out from the given alternatives.
(NOTE: Operations should be performed on the whole numbers, without breaking down the number into its constituent digits. E.g.13 − Operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)
