WebSep 5, 2024 · Exercise 5.1. 1. Consider the sequence of numbers that are 1 greater than a multiple of 4. (Such numbers are of the form 4 j + 1 .) 1, 5, 9, 13, 17, 21, 25, 29,... The sum of the first several numbers in this sequence can be expressed as a polynomial. ∑ j = 0 n 4 j + 1 = 2 n 2 + 3 n + 1. WebI understand the principle of finite induction, but my book then mentions that there is a variant of the first where requirement b is changed to If k is a positive integer such that 1, 2, …, k belong to S, then k + 1 must also be in S.
