Put the steps of a proof for the following claim in the proper order:
4 + 8 + 12 +
+ 4n = 2n(n + 1)
+ 4k + 4(k + 1) = 2k (k + 1) +4(k + 1)
2 (k + 1) (k +2)
• 4+8+ 12 + ..
+ 4k = 2k (k + 1).
Assume 4 + 8 + 12 +
v Let n = 1. Clearly,
4 = 2(1)(1+ 1).
v WTS: 4 +8+ 12 + + 4k + 4(k + 1) = 2 (k + 1) ((k
+ 1)
+ 1)
