Question

The sum of three consecutive number is 216. Find the number. with process​

Answer 1

Let the smallest of three consecutive even integers be x. Thus other two integers are x + 2 and x + 4

The sum of these three integers is 216. Accordingly

x + x + 2 + x + 4 = 216

3x + 6 = 216

3x = 216 - 6

3x = 210

x = 210/3

x = 70

The smallest consecutive even number is 70. Thus other two numbers are

1st number x + 2 = 70 + 2 = 72

2nd number x + 4 = 70 + 4 = 74

The three consecutive even numbers are 70, 72 and 74.

Answer: The three consecutive even numbers are 70, 72 and 74.

Answer 2

Step-by-step explanation:

$\huge\fbox\pink{❥❥Answer❥❥}$

let the three consecutive number be x+1,x+2,x+3

According to the question:-

x+1+x+2+x+3=216

=>x+x+x+1+2+3=216

=>3x+6=216

=>3x=216-6

=>3x=210

=>x=210/3

=>x=70

so the three consecutive numbers are x+1=70+1=71, x+2=70+2=72 ,x+3=70+3=73

and 71+72+73=216
