Step-by-step explanation:
that what i think
The formula is x1+x2 divided by 2 and y1+y2 divided by 2.I hope this is what you where looking for
3 consecutive means
x, x+1, x+2
OR
x, x-1, x-2
the equation based on givens and first equation is:
2(x) + 2(x+1) = 69 - (x+2)
4x + 2 = 67 - x
5x = 65
x = 13
so the largest would be x+2 or 15
