. 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

purpose of this project is to develop Wallis's formula. Forn 0.1,2,.., define The 6. Prove that 2e12 12 3-3-5-5-7.7-(2n (2n (2n 1)m 2-2.4.4-6-6(2n)(2n) 2 Parts 5 and 6 yield Wallis's formula: 2-2.4-4-6-6(2n)(2n) niin 1-3-3-5-5-7-7 (2n-I)(2n-1)(2n + 1) = 2. lim Wallis's formula gives as an infinite product, defined as the limit of partial products, in much the same way we defined the infinite sum as the limit of partial sums.
