= = 3. (3 pts) Let T(n) = 5 for n = 1, and for all n z 2, T(n) T(n-7) + 4n+ 3. Solve this recurrence using the mathematical induction method. (i.e., You need to guess a solution - explicit solution of T(n) (you need to specify all coefficients, do not use 0, 12, or ), and assume that the guess is true for n=k. Then prove that it is also true for n=k+7. You also need to prove that your guess is true for the base case
