Suppose I have a list of the following:
list={{1,2},{1,6.5},{1,6},{1,0}....{1,36}}
.
Let say the Length of the list is 300. I would like to sum the first member of the first case of the list by 0. The first member of the second case by 1. The first member of the third case by 2 and so on. The result would be the following:
{{1,2},{2,6.5},{3,6},{4,0},...{300,36}}
