Write three consecutive numbers starting with number n+1, where n is natural number. Find the sum of those numbers and prove tha

netineya [11]

Consecutive numbers differ by one, which means that if you start with a certain integer $x$ , you obtain the next integer by adding one.

So, if you start with $n+1$ , the three consecutive numbers are

$n+1,\quad (n+1)+1 = n+2,\quad (n+2)+1 = n+3$

The sum of these three numbers is

$(n+1) + (n+2) + (n+3) = 3n+6$

This number is divisible by 3 because you can write it as

$3n+6 = 3(n+2)$

Note that this is true in general: the sum of three consecutive numbers is always divisible by three, because it is three times the middle number.

1) 3/5=9/x (cross multiply)
3x=5(9)
3x=45
x=15

2) 2/4=x/12 (cross multiply)
 2(12)=4x
 24=4x
 6=x

3) 10/x=5/9 (cross multiply)
10(9)=5x
90=5x
18=x

4) 5/6=x/18
5(18)=6x
