well you need to convert into pounds from kg or inches into meters. then you could go:
as W=mgh, m=60kg, g=9.81ms^-2, h=(height of each step)
break an equation into each step, add all the steps together.....
then we could say:
9.81x60kg(6in+ 12in+ 18in+ 24in etc etc)......twelve times to gain the total number of steps. adding all together will gain the total work done.

What in consecutive numbers?
You seem to be asking what consecutive numbers are. Consecutive numbers are integers in order, with each one being exactly 1 higher than the previous one. To put it another way, each number is the next higher integer after the previous one. For example, 3, 4, 5, 6, 7 are consecutive numbers. One can also refer to consecutive even numbers, consecutive odd numbers, consecutive square numbers, etc. In each case, each number in the sequence is the next higher number of the specified kind after the previous one. For example, 12, 14, 16, 18 are consecutive even numbers.
