trial and error; 5x7=35 9x9=82, difference of 47. not big enough difference. 7x9=63 11x11=121. differenence of 58, which is too big. sorry, but this means there is not answer.
Find 3 consecutive numbers where the product of the smaller two numbers is 19 less than the square of the largest number.

3, 5, 7
6, 8, and 10. To figure this one out, it is trial and error, so pick random numbers. 4x6=24 8x8=64, difference of 40, not big enough. 6x8=48 10x10=100 difference of 52. So, the right answer is 6, 8, and 10.
4,6,8,10ok, that's kool, now what the hell is the answer to this mind blower?!?!The square of 9 more than a number is equal to 9 more than the square of the number What is the number? the answer is 10,8,6 and 4

Let the numbers be ;- n, n+1, n+2. Hence n(n+1) is 19 less than (n+2)^(2) It follows;- n(n+1)+ 19 = (n+2)^(2) Multiply out the brackets. n^(2) + n + 13 = n^(2) + 4n + 4 Collect 'like' terms. n^(2) - n&(2) + 4n - n = 13 - 4 Add 3n = 9 n = 3 n+ 1 = 4 n +2 = 5 Hence 3,4, & 5 are the consecutive numbers.
