I'm probably missing something, but is this sort of what you are
looking for?
<code>
nlines = 188
new_array = [] # this creates a list
for i in range(nlines):
new_n = 1.1 ** i
mean = (new_n + i) / 2
new_array.append(mean)
</code>
If you wanted a cumulative mean of the values, then you'll have to
change it slightly of course, probably by using a nested loop.
Hopefully this isn't a homework question, but even if it is, it's an
interesting exercise.
