Proof: By induction.Let P(n) be “the sum of the first n powers of two is 2n – 1.” We will show P(n) is true for all n ∈ ℕ. For our base case, we need to show P(0) is true, meaning the sum of the first zero powers of two is 20 – 1. Since the sum of the first zero powers of two is 0 = 20 – 1, we see WebThis problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts.

WebIn calculus, induction is a method of proving that a statement is true for all values of a variable within a certain range. This is done by showing that the statement is true for the first term in the range, and then using the principle of mathematical induction to show that it is also true for all subsequent terms. WebMathematical Induction is very obvious in the sense that its premise is very simple and natural.
