Three of the following number triples follow the same rule. Select the one that does NOT belong.
- 2 : 4 : 16
- 3 : 6 : 36
- 4 : 8 : 64
- 5 : 10 : 120
Correct answer: 5 : 10 : 120
Solution
The pattern is n : 2n : n-squared. For 2,4,16; 3,6,36; 4,8,64 it holds. For 5 it should be 5:10:100, but 120 is given, so this triple is the odd one out.
