Fibonacci Sequence How to Sum the Average?

madkilah28 (1)
Help to get the Average of the Last Final results of the 3 Fibonacci Sequence.

I need to create a program that will ask the user to continuously enter a terms number until the user entered 3 fibonacci sequence. And then it will
print out the average of all the numbers entered.


I only need is to get the Average of the 3 final results or the last results of the 3 Fibonacci sequence.

Here's a code of Fibonacci but i don't know how to complete it.

Thanks in advance.

If a user enters 2, 4 and 6, you'll print
1 1
1 1 2 3
1 1 2 3 5 8
and the average you want is (1+3+8)/3. Did I understand you correctly?

If so, have variables int last, last1, last2;. After every for loop, write last/*or last1 or last2*/ = c;. Then your average is (last+last1+last2)/3.

By the way, note that this is a good place to use arrays or functions as you have 3 of everything.
