Determine what the next equation would be, and verify that it is indeed a true statement. Describe the pattern.
9x9=81
99x99=9801
999x999=998,001
I know the next sequence is 9999x9999=99980001

I just don't know which pattern this is called.

Notice the nine leading increase in number each time by one, and the trailing zeroes increase by one.
Answered by Kelly
Yes, I did notice that as well. I just didn't know the name of that pattern, is it a trailiing pattern?
