How is the “limiting value” related to the original 3 numbers?

Which 3 numbers give you a “nice” limiting value?

Does the order of the 3 numbers matter?

Is there a pattern in the limiting value if the original 3 numbers are consecutive?

How about if they are in a sequence?

How about if some of the numbers are the same?

What about square numbers, Fibonacci numbers, etc ?...

Can you convince people using algebra?

Try starting with 2 numbers

Or 4

Or 5

Try drawing a graph of each of the values
Which graphs oscillate?
Which graphs approach like a staircase?
