WebSep 5, 2024 · We have now proved conditions (a) and (b) of Theorem 1.3.1. Therefore, by the principle of mathematical induction we conclude that 1 + 2 + ⋯ + n = n(n + 1) 2 for all n ∈ N. Example 1.3.2 Prove using induction that for all n ∈ N, 7n − 2n is divisible by 5. Solution For n = 1, we have 7 − 2 = 5, which is clearly a multiple of 5. WebSum of the First n Natural Numbers.

WebThe parseInt () converts the numeric string value to an integer value. The for loop is used to find the sum of natural numbers up to the number provided by the user. The value of sum is 0 initially. Then, a for loop is used to iterate from i = 1 to 100. In each iteration, i is added to sum and the value of i is increased by 1. WebBasically, the formula to find the sum of even numbers is n (n+1), where n is the natural number. We can find this formula using the formula of the sum of natural numbers, such as: S = 1 + 2+3+4+5+6+7…+n S= n (n+1)/2 To find the sum of consecutive even numbers, we need to multiply the above formula by 2.
