Sum of 3 consecutive even no.'s is 38 more than the 1st no. of the series. Find the middle no.?
Answer/Solution
18
Steps/Work
Let the numbers be x, x+2 and x+4 then
x + x+2 + x+4 = x+38
3x + 6 = x + 38
2x = 32
\inline \therefore x = 16
\inline \therefore Middle number = x + 2 = 16+2 = 18
E
x + x+2 + x+4 = x+38
3x + 6 = x + 38
2x = 32
\inline \therefore x = 16
\inline \therefore Middle number = x + 2 = 16+2 = 18
