I came up with this pattern for an extra credit question for my High School English students. None of them figured it out, but I'll let you have a shot at it. The great thing about coming up with your own pattern is that none of you can google for it.
What is the next number?1, 2, 4, 5, 7, 8, 11, 12, 20, 70, ?
The deviant who figures out the next number and
correctly explains the pattern gets a free 8x12 print
from any of my photos.
It's quite an easy pattern, no complex math required. So don't get into any strange formulas.
Remember, give both the number and its pattern.
