Guess formula and prove by induction Σ(-1)-F2-1 1=1
Induction proofs. a. Prove by induction: n sum i^3 = [n^2][(n+1)^2]/4 i=1 Note: sum is intended to be the summation symbol, and ^ means what follows is an exponent b. Prove by induction: n^2 - n is even for any n >= 1 10 points 6) Given: T(1) = 2 T(N) = T(N-1) + 3, N>1 What would the value of T(10) be? 7) For the problem above, is there a formula I could use that could directly calculate T(N)?...
please show by using the following version of induction: 2.3.28 Prove the formula for the sum of a geometric series: Can - 1) an-1 +an-2 + ... +1 a-1 • BASIS STEP: Show that P(n) is true for n = no. • INDUCTIVE STEP: Assume that P(n) is true for some n no. (This is called inductive hypothesis). Then show that the inductive hypothesis implies that P(n + 1) is also true.

Suppose you want to prove the following: 1/2 + 1/4 + 1/8 + . . . + 1/2 n < 1 Try to prove this “directly,” using induction. I assume your attempt will fail. Describe the difficulty you run into. Now try another approach: (a) By experimenting with small values of n, guess an exact formula for the sum. (b) Prove that your guess is true. (c) As a corollary conclude: 1/2 + 1/4 + 1/8 + . . ....

Prove using the Basic Principle of Mathematical Induction: For every positive integer n 24 | (5^(2n)- 1)
Prove by induction that for every positive integer n, the following identity holds: 1+3+5+...+(2n – 1) = np. Stated in words, this identity shows that the sum of the first n odd numbers is n’.
