х+(х+1)+(х+2)=84
3х=81
х=27(меньшое число)
27+1=28(среднее число)
27+2=29(большее число)

Answer 2

Finding the Sum of the Next 3 Even Numbers

To find the sum of the next 3 even numbers, we can start by representing the first even number as x. The next two even numbers would then be x + 2 and x + 4.

According to the given information, the sum of these three even numbers is 84. We can set up the equation as follows:

x + (x + 2) + (x + 4) = 84

Simplifying the equation, we get:

3x + 6 = 84

Subtracting 6 from both sides of the equation:

3x = 78

Finally, dividing both sides of the equation by 3:

x = 26

Therefore, the first even number is 26, and the next two even numbers are 28 and 30.

So, the three even numbers that add up to 84 are 26, 28, and 30.

Answer:

The three even numbers that add up to 84 are 26, 28, and 30.
