*urgent first answer gets brainliest! *
the digits of a two digit number add up to 7, but when the digits are reversed, the original number increases by 9. what is the original number?

the original number is 34. 34 plus 9 is 43.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
