Shouldn't the answer be 57? i.e. range of 5 consecutive even numbers is 9 --> 2,3,4,5,6,7,8,9,10
If we count the odd numbers in-between, we get 4(5-1), hence 5+4.

Thanks in advance for your clarification.

With a series of evens, you get ranges like:
2 Evens --> ( 2,4) --> Range 2
3 Evens --> ( 2,4,6) --> Range 4
4 Evens --> ( 2,4,6,8) --> Range 6
5 Evens --> ( 2,4,6,8,10) --> Range 8

It seems that the range and the x number of evens have a formula like:
range = 2*(x-1)
If x = 29 --> 2*(29-1) = 2*28 = 56

The Range of a set refers to the difference between the highest and lowest number in the set.

In your example with 5 consecutive even numbers, the range is (10 - 2) =8
