We have the final answer BUT one of the questions was a number sequence and we don't understand why.

16, 24, 36, ??, 81

The missing number was 54.

Anyone understand why?

PS. There was a hint as well which was "Where is their other half?"

Thanks in advance

Half of 16 is 8. 16 + 8 =24
Half of 24 is 12, 24 + 12 = 36
Half of 36 is 18 36 +18 = 54
16 + 8 = 24
24 + 12 = 36
36 + 18 = 54
54 + 27 = 81
Add each number to half of itself

The claims telephone number does not work,I finished the quiz and phoned the number on the back of the dvd cover 0905 168 0060 and all you get is a BT message saying number not recognised , check & try again! Well thats just great! Anyone else having this problem?
The answer is 54 because it is half of 36 (18) so the sum goes 36 + 18 = 54 - then half of 54 is 27 + 54 = 81.
