Is the formula given the same as the code?

Hey guys. I’m currently having a disagreement with a lecturer over this assignment question. I believe that the code should be changed to t=0:6 to match the formula they have given. We were given a morality table so do not worry about dx or lx as those are set variables. Any clarification on this would be greatly appreciated. Thank you, O.H

Since the exponents range from -1 to -7, that means you will need 7 different values for t. One of the ways to achieve that is indeed having t=0:6.
Neither is infinite (as the summation indicates), but this might be a reasonable approximation for your application.

Thank you so much! That is exactly what I wanted to hear. I knew the lecturers code was wrong!
It’s not infinite as dx can only go up to d99 therefore should stop at the 7th variable.
Thanks again!

Maybe the infinity symbol should be replaced by that upper bound:

Actually, I guess technically it is bounded to infinity, but if x>100 then dx and lx = 0. Either way you would get the same answer
