Question 1081250: Which answer shows the correct 1st step to prove the following by mathematical induction?
3 + 11 + 19 + 27 + � + (8n - 5) = n(4n - 1)
A.) 3 + 11 + 19 + 27 + � + (8 � 1 - 5) = 1(4 � 1 - 1)
B.) 8 � 1 - 5 = 1(4 � 1 - 1)
C.) 3 + 11 + 19 + 27 + � + (8k - 5) = k(4k - 1)
D.) 3 + 11 + 19 + 27 + � + (8k - 5) + [8(k + 1) - 5] = (k + 1)[4(k + 1) - 1]
