Question

The sum of 3 consecutive even numbers is 270. What is the first number in this sequence?

Answer 1

let the 3 consecutive even numbers are
2x -2, 2x, 2x+2

ATQ

2x-2 +2x +2x+ 2 = 270
6x = 270
x= 45

therefore the numbers are 88 ,90 , 92

Answer 2

let the three consecutive numbers be

X,X+2,X+4

ACQ

X+X+2+X+4=270

3x+6=270

3x=270-6

3x=264

X=264/3

X=88

so the first number is 88

series:- 88,90,92
