Find three consecutive numbers such that 3 times the middle one shall be greater than the sum of the other two by 15.
:
Three consecutive numbers: x, (x+1), (x+2)
:
" 3 times the middle one shall be greater than the sum of the other two by 15."
3(s+1) = x + (x+2) + 15
:
3x + 3 = 2x + 17
:
3x - 2x = 17 - 3
:
x = 14, 15, 16 are the three numbers:
:
:
Check in the statement:
3 times the middle one shall be greater than the sum of the other two by 15.
3(15) = 14 + 16 + 15
