To find the middle number, divide 1542 by 3: you will get middle number == 514. Then the smaller number is 512 and the larger number is 516. ANSWER. The numbers are 512, 514, 516.
Explanation Let x be the middle number. Then the numbers are (x-2), x and (x+2). Adding them, we get (x-2) + x + (x+2) = 3x. It gives us an equation 3x = 1542, which we used above to find the middle number.
