Question

Average of 4 consecutive even numbers is 80 find 3 number

Answer 1

Let four consecutive even numbers be

p ,  p + 2 ,  p + 4  ,  p + 6

$80 = \frac{p+p+2+p+4+p+6}{4}$

80 × 4 = 4p + 12

80 × 4 = 4( p + 3)

$\bf\huge\frac{80\times4}{4} = p+3$

80 = p + 3

80 - 3 = p

77 = p

Consecutive numbers :-

77     ,     79     ,     81
