Solve: find three consecutive even integers such that the sum of the smallest number and twice the middle number is 20 more than the largest number?

8

Step-by-step explanation: 6,7,8 are the consecutive integers because 6+7(2)=20

We are given

Let's assume

smallest even integer =x

Since, each even integers are difference of 2

so, middle term =x+2

so, largest term =x+2+2=x+4

the sum of the smallest number and twice the middle number is 20 more than the largest number

so, we get

now, we can solve for x

Divide both sides by 2

so, smallest even integer=10

middle even integer=12

largest even integer=14............Answer
