Sagot :
(x) + (x+2) + (x+4) + (x+6) + (x+8) = 85
5x+20 = 85
5x=85-20
5x=65
x=13
sum of the last 2 = (x+6) = 13 + 6 =19
= (x+8) = 13 + 8 = 21
19+21 =40
5x+20 = 85
5x=85-20
5x=65
x=13
sum of the last 2 = (x+6) = 13 + 6 =19
= (x+8) = 13 + 8 = 21
19+21 =40
I just do 85÷5=17 ..... 17 is mid..
13+15+17+19+21=85
so 19+21=40
SO THE ANSWER IS 40
13+15+17+19+21=85
so 19+21=40
SO THE ANSWER IS 40
