Answer

B. The next equation would be 5^{2} - 4^{2} = 5 + 4, and it is a true statement. Explanation 1. Identify the pattern The left side is n^2 - (n-1)^2, and the right side is n + (n-1). 2. Write formula and simplify LHS **Formula:** n^2 - (n-1)^2 = n^2 - [n^2 - 2n + 1] = 2n - 1. Right side: n + (n-1) = 2n - 1. They match → always true. 3. Find the next equation After n=4, next is n=5: 5^2 - 4^2 = 5 + 4. 4. Verify 25 - 16 = 9 and 5 + 4 = 9 → true.

Explanation

1. Identify the pattern <br /> The left side is $n^2 - (n-1)^2$, and the right side is $n + (n-1)$. <br /><br />2. Write formula and simplify LHS <br />**Formula:** $n^2 - (n-1)^2 = n^2 - [n^2 - 2n + 1] = 2n - 1$. <br />Right side: $n + (n-1) = 2n - 1$. They match → always true. <br /><br />3. Find the next equation <br /> After $n=4$, next is $n=5$: $5^2 - 4^2 = 5 + 4$. <br /><br />4. Verify <br />$25 - 16 = 9$ and $5 + 4 = 9$ → true.
