Question 1035810: For a proof by induction of the math statement below, identify the correct step for proving the theorem is true for n = k + 1.
3^2+6^2+9^2+...
You can put this solution on YOUR website! The formula for this sequence 3^2+6^2+9^2+... is (3n)^2 when n starts at one.
When I substitute k+1 for n i get (3(k+1))^2 or (3k+3)^2 when k starts at zero for the first number of the sequence.
