Congrats to the TWO students who answered last week's question about the earthquake. The answer to the question was the square root of 10 (or about 3.1). This week's question is a little easier, I hope. It is...
Suppose the numerical pyramid below kept on going. What would be the sum of the numbers in the 10th row?
7 9 11
13 15 17 19
Email your answer to this question to firstname.lastname@example.org by Friday, April 27 at 2:00. Good luck!
(I can't get the pyramid to come out looking like a pyramid when I publish the post. Use your imagination.)
