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.
. 1. Prove by induction that for all integers n≥1, 4+8+12+...+4n = 2n^2+2n 2. A number a is divisible by b if the remainder of dividing a by b is zero. For example 10 is divisible by 5 but 11 is not divisible by 5. Prove by induction that for all integers n≥1,11^n - 6 is divisible by 5. 3. Prove by induction that for all integers n ≥ 1, 3^n ≥ 2^n+n^2

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 + . . ....
