a x (a +1) = (a + 2)^2 - 28 ie a^2 + a = a^2 + 4a + 4 - 28 ie a^2 -a^2 + a - 4a = 4 - 28 ie -3a = -24 ie a = 8 Numbers are 8, 9 and 10. Check: 8 x 9 = 10^2 - 28 so 72 = 100 - 28 OK
8,10,12
16, 17 and 18
the answer is 6
6 and 8. 6 * 8 = 48 6 * 6 = 36 48 - 36 = 12
Let the 3 consecutive number be represented by n, (n + 1) and (n + 2) Then, n(n + 1) + 37 = (n + 2)2 n2 + n + 37 = n2 + 4n + 4 3n = 33 n = 11 The three numbers are 11, 12 and 13.
Find 3 consecutive numbers where the product of the smaller two numbers is 19 less than the square of the largest number.

Surely the question is wasn't meant to say what it literally said, but a solution to its literal statementis still possible.The two consecutive numbers are: 18 and 19.The smaller two numbers are: 18 and 19.Their product is 342 .The largest number is 19.Its square is 361.342 is 19 less than 361.
the answer is 6
The product of 2 consecutive positive number is 48. Find the 2 numbers
