Recurrence with solution 2 n+1 - 1 induction
WebWe can prove easily in induction, that T ( n) = c + ∑ i = 1 n i. Assume correctness for n, we will prove for n + 1. Clearly, T ( n + 1) = T ( n) + ( n + 1) = c + n + 1 + ∑ i = 1 n i = c + ∑ i = 1 n + 1 i. A nice result you are probably familiar with, if you learned about arithmetic progression series, is that ∑ i = 1 n i = n ( n + 1) 2 WebSubstituting this into the original recurrence, we see that a2n+1 + b = a2n+1 +2b 1 ()b = 2b 1 ()b = 1 But then x 1 = 2a+1 = 2 ()a = 1 2. The solution is therefore xn = 1 2 2n +1 = 2n 1 +1 …

Prove by induction that C (n) = 4 3 n + 1 − 2 n − 3 for all n ≥ 0. (Induction on n.) Let f (n) = 4 3 n + 1 − 2 n − Base Case: If n = 0, the recurrence relation says that C (0) = 0, and the formula says that f (0) = 4 3 , so they match.
WebWe assume this and try to show P(n+1). That is, we want to show fn+1 rn 1. So consider fn+1 and write fn+1 = fn +fn 1: (1) We now use the induction hypothesis, and particularly fn rn 2 and fn 1 rn 3. Substituting these inequalities into line (1), we get fn+1 r n 2 +rn 3 (2) Factoring out a common term of rn 3 from line (2), we get fn+1 r n 3(r+ ...
