Observe the following equation: 9 × 0 + 1 = 19 × 1 + 2 = 119 × 2 + 3 = 219 × 3 + 4 = 319 × 4 + 5 = 41 According to the law reflected in the number table, we guess that the nth equation (n is a positive integer) should be () A. 9(n-1)+n=10(n-1)+1B. 9n+n=(n-1)+1C. 9n+(n-1)=n2-1D. 9n+n+1=10n+1

Observe the following equation: 9 × 0 + 1 = 19 × 1 + 2 = 119 × 2 + 3 = 219 × 3 + 4 = 319 × 4 + 5 = 41 According to the law reflected in the number table, we guess that the nth equation (n is a positive integer) should be () A. 9(n-1)+n=10(n-1)+1B. 9n+n=(n-1)+1C. 9n+(n-1)=n2-1D. 9n+n+1=10n+1

By finding the rule, we can see that the nth equation (n is a positive integer) should be 9 (n-1) + n = 10 & nbsp; (n-1) + 1
