Which of the following shows the correct first step in proving the following by mathematical induction?
3 + 11 + 19 + 27 +...+(8n - 5) = n (4n - 1)
3 + 11 + 19 + 27 +...+ (8 • 1-5) = 1 (4.1-1)
8.1-5=1(4.1-1)
3 + 11 + 19 + 27 +...+ (8k - 5) = k (4k-1)
3 + 11 + 19 + 27 +...+ (8k - 5) + [8 (k+ 1) - 5] = (k+ 1) [4 (k+ 1) − 1]
