Find the next number. 2, 6, 30, 210, ?
1890
Because the numbers grow very fast, look at how each term is produced from the previous one by multiplication rather than by adding a difference.
From 2 to 6 the factor is 3, since \(2\times3=6\).
From 6 to 30 the factor is 5, since \(6\times5=30\), and from 30 to 210 the factor is 7, since \(30\times7=210\).
The multipliers so far are 3, 5, 7, which are consecutive odd numbers, so the next multiplier must be 9.
Applying it to the last given term gives \(210\times9=1890\).
The concept is a product series in which the growing factors themselves follow a simple run of odd numbers. Hence the next number is 1890.

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)
