Question

The sum of 5 consecutive even number is 360 . What is the third number in the sequence

Answer 1

Answer:

Third no. in the sequence= 72

Step-by-step explanation:

Let five no.'s be x, x+2, x+4, x+6, x+8.

Sum of 5 consecutive even numbers=360

x+x+2+x+4+x+6+x+8=360

5x+20=360

5x=360-20

5x=340

x= 68

So, First no. =x=68

Second no.=x+2=68+2=70

Third no.=x+4=68+4=72

Forth no.=x+6=68+6=74

Fifth no.=x+8=68+8=76

Answer 2

Step-by-step explanation:

let the 1st number be = x

So , x +x+2+x+4+x+6+x+8 = 360

5x + 20 = 360

5x = 360 - 20= 340

x = 340/5

x = 68

x= 68

x+2=70

x+4=74

x+6=76

x+8=78
