Question
The sum of two consecutive numbers divided by their positive difference is equal to 9. Find the largest number.
Answers
the difference between any two consecutive numbers is just 1.
so, x + x+1 = 9
x = 4
the next number is 5
so, x + x+1 = 9
x = 4
the next number is 5
or
n + n-1 = 9
2 n = 10
n = 5
same old boring solution :)
n + n-1 = 9
2 n = 10
n = 5
same old boring solution :)
or, following the wording:
(x + x+1)/(x+1 - x) = 9
2x +1 = 9
x = 4
same old
(x + x+1)/(x+1 - x) = 9
2x +1 = 9
x = 4
same old
Thanks for the explanation
