the correct answer is the smaller number is:127 and the bigger number is:128

Explanation:

Answer 2

n is smaller, n + 1 is larger

Explanation:

First, make the equation.

2(n + n+1) = 510

Then, simplify.

2(2n + 1) = 510

Distribute.

4n + 2 = 510

Solve.

n = 127

The smaller number is n (127) and the larger number is n + 1 (128).
