Prove by induction that ∑ k n n+1 / 2
WebbBy the Principle of Mathematical Induction, ∑ (-1/2) j = [2 n+1 + (-1) n ]/ (3×2 n) from j=1 to n, whenever n is a nonnegative integer. Related exercises: a) Find a formula for 1/ (1×2) + 1/ (2×3) + 1/n (n+1) by examining the values of this expression for small values of n. b)Prove the formula you conjectured in part (a) WebbShow that p (k+1) is true. p (k+1): k+1 Σ k=1, (1/k+1 ( (k+1)+1)) = (k+1/ (k+1)+1) => 1/ (k+1) (k+2) = (k+1)/ (k+2) If this is correct, I am not sure how to finish from here.
