Three of the following four are alike in a certain way and thus form a group. Which is the one that does NOT belong to that group? NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 - Operations on 13 such as adding/deleting /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)
9 - 44 - 218
The common rule is to multiply by 5 and add 1 at each step:
\(6\to31\to156;\quad13\to66\to331;\quad16\to81\to406\)
\(9(5)+1=46\ne44;\quad44(5)+1=221\ne218\)
Thus 9 – 44 – 218 is different.
