Three of the following four number-pairs are alike in a certain way and one is different. Select the one that is different.

5 : 100

THE LOGIC;

( \( {(1st number}^{3} \) - \( {(1st number}^{2} \) = 2nd number )

1) 4 : 52,

\( {(4}^{3} \) - \( {(4}^{2} \)

64-16 \(\neq \) 52

2) 5 : 100,

\( {(5}^{3} \) - \( {(5}^{2} \) 

125-25 = 100

3) 7 : 294,

\( {(7}^{3} \) - \( {(7}^{2} \) 

343-49 = 294

4) 6 : 180,

\( {(6}^{3} \) - \( {(6}^{2} \) 

216-36 = 180

Thus, 4 : 52 is the odd one.
