I need to write a procedure that adds all multiples of 5 and 7 less than an arbitrary number. I was thinking something maybe with mod? I am very new to Maple. 

On in this same assignment, we are also supposed to generate a sequence using the Fibonacci equation but from an arbitrary pair of initial conditions. So if there are some parallels between these two problems, I would love to learn from that angle.  

We recently in class learned about do loops, so if there is a way to attack these problems with do loops, I would like to hear!

I need to change the following continued fractions into rational numbers using the cfrac function:

1)  [1 , 2]               2) [1, 1, 2]                3) [1, 1, ,1, 2]

Thanks,

Sara
