Let the numbers be 7a , 7a + 7 and 7a +14
According to question,
7a + 7a +7 +7a + 14 = 0
=> 21a + 21 = 0
=> 21a = -21
=> a = -1
First number = 7(-1) = -7
Second number = 7(-1) + 7
= -7 + 7
= 0
Third number = 7(-1) +14
= -7 + 14
= 7
According to question,
7a + 7a +7 +7a + 14 = 0
=> 21a + 21 = 0
=> 21a = -21
=> a = -1
First number = 7(-1) = -7
Second number = 7(-1) + 7
= -7 + 7
= 0
Third number = 7(-1) +14
= -7 + 14
= 7
