Question: Describe the error in finding the sum. 1. 2. 4 (3 + 2k?) = 3 + 2k? k=1 k=1 = 3 + (2 + 8

Describe the error in finding the sum.

1.

4 (3 + 2k?) = 3 + 2k? k=1 k=1 = 3 + (2 + 8 + 18 + 32) = 63

2.

3 Σ(-1)

4 (3 + 2k?) = 3 + 2k? k=1 k=1 = 3 + (2 + 8 + 18 + 32) = 63 3 (-1)"n! - (-1 ) (1) + (1) (2) + (-1) (6) 0 = -5
