Question

the sum of four consecutive even no. is 276 . find the no.

Answer 1

let the no be x,x+2, x+4,x+6
x+x+2+x+4+x+6 = 276
4x +12 =276
4x=276-12
4x=264
x=264/4= 66

consecutive no.s are 66,68,70,72
mark me as brainliest

Answer 2

Let the fist number be x

Let the second number be x + 2

Let the third number be x + 4

Let the fourth number be x + 6


x + x + 2 + x + 4 + x + 6 = 276

4x + 12 = 276

4x = 276 - 12

4x = 264

x = $\frac{264}{4}$

x = 66

1st number => x = 66

2nd number = x + 2 = 66 + 2 = 68

3nd number = x + 4 = 66 + 4 = 70

4th number = x + 6 = 66 + 6 = 72
