The correct Answer is:
To solve the problem step by step, we will analyze both statements and prove their validity. ### Step 1: Analyze Statement 2 Statement 2 claims that the difference between the sum of the first \( n \) even natural numbers and the sum of the first \( n \) odd natural numbers is \( n \). #### Sum of the First \( n \) Even Natural Numbers The first \( n \) even natural numbers are: \[ 2, 4, 6, \ldots, 2n \] The sum \( E \) of these numbers can be calculated using the formula: \[ E = n \times \left(\frac{2 + 2n}{2}\right) = n \times (n + 1) = n(n + 1) \] #### Sum of the First \( n \) Odd Natural Numbers The first \( n \) odd natural numbers are: \[ 1, 3, 5, \ldots, (2n - 1) \] The sum \( O \) of these numbers can be calculated using the formula: \[ O = n^2 \] #### Difference Between the Sums Now, we find the difference \( E - O \): \[ E - O = n(n + 1) - n^2 = n \] Thus, Statement 2 is true. ### Step 2: Analyze Statement 1 Statement 1 claims that the difference between the sum of the first 100 even natural numbers and the sum of the first 100 odd natural numbers is 100. #### Calculate for \( n = 100 \) Using the results from Statement 2, we can substitute \( n = 100 \): \[ E = 100(100 + 1) = 100 \times 101 = 10100 \] \[ O = 100^2 = 10000 \] Now, we find the difference: \[ E - O = 10100 - 10000 = 100 \] Thus, Statement 1 is also true. ### Conclusion Both statements are true, and Statement 2 provides a correct explanation for Statement 1.
