On my classpad , I wrote a program that uses 3 sequences to make a sequence table of n=150 (or more) .
The problem is that the execution of the program takes a lot more time (more than 3 minutes) than the algebra Fx 2.0 which takes less than a minute.
But I noticed that on the algebra, the numbers are rounded up to 9 decimals. On the classpad they are rounded to nearly 15 numbers.
So I used the "fround" function on the class pad to round the numbers to 9 decimals.
The difference in time was nearly 10 seconds.
The overall time is still very high, so please someone help me to speeden up the process.
A pic of the program is available , how can I upload it?
(It is really important for me because this program is needed in exams and I have one in a couple of days

Thanks for the help
