The sum of three consecutive multiples of 7 is zero find the integers​

Answer»

Step-by-step explanation:

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
