The product of two adjacent even numbers is 168. Solve these two even numbers by equation

The product of two adjacent even numbers is 168. Solve these two even numbers by equation

Let these two even numbers be x, x + 2
x（x+2)=168
x^2+2x-168=0
(x+14)(x-12)=0
x=-14 x=12
x+2=-12 x+2=14
These two even numbers are 12 and 14 or - 14 and - 12

The sum of two adjacent even numbers is 194. What are the two even numbers? The equation

x=96y=98

There are three consecutive odd numbers. If the first number is a, the other two numbers are a______ And______ The average of these three consecutive odd numbers is______ ．

If there are three consecutive odd numbers, the first number is a, then the odd number in the middle is a + 2, and the largest odd number is a + 2 + 2 = a + 4; the average of the three numbers is: [a + (a + 2) + (a + 4)] 3, = (3a + 6) △ 3, = (a + 2) × 3 △ 3, = a + 2. So the answer is: a + 2, a + 4, a + 2
