I just add a fascinating conversation on twitter, and I made a video to pose it to you. In particular, if you’ve got upper elementary or middle school students (or high school, or college), and want to explore whether this pattern keeps working, I’d love to hear how it goes.

Here’s the original tweet, and my video synopsis below.

I like this 1: find the sum of 10 numbers with a pattern of: a+b=c, b+c=d, c+d=e etc.
Take the 7th answer (g) & multiply by 11
Example:
a) 12
b) 2
c) 14
d) 16
e) 30
f) 46
g) 76
h)122
I) 198
j)320
Ans:836
Divide the answer by 7th number it will always b 11.#Math #DOMATH
