Part D: Exploring Pascal's Triangle 1. Fill-In the missing numbers in Pascal's Triangle. See 2. Find the sum of each row in Pascal's Triangle. Describe the pattern. 1, 2, 4, 8, 16... Power of 2n 1 1 1 1 2 1 1 3 3 1 6 1 4 6 4 1 5 10 10 5 1 1 6 15 20 15 6 1 1 7 21 35 21 35 7 1 1 .8 2856 70 56 288 1 3. Use these sums to find the 36 84 126 126 84 36 9 sum of the first 20 rows. 1 10 45 120 210 252 210 120 45 10 1 4. Triangular numbers are numbers that can be drawn as a triangle. For example, 3 is a triangular number and can be drawn like this. 6 is a triangular number and can be drawn like this. Find and represent the next two triangular numbers. Where can you fnd triangular numbers in Pascal's Triangle? 5. Color all of the even numbers in Pascal's Triangle. Where have we seen this pattern before?
