let as consider the unknown number be x
x , x+7.x+14,x+21 are the four consecutive number
x , x+7.x+14,x+21 here we have taken +7,+14,+21 because the x value is constant we the number is increased by 7 it makes the consecutive number
given is that
The sum of four consecutive multiples of 7 = 70.
x +x+7+x+14+x+21= 70
4x+42= 70
4x= 70-42
4x= 28
x= 28/7
x= 7
x =7
x+7= 7+7 = 14
x+14= 7+14= 21
x+21= 7+21=28
verification
x + x+7+x+14+x+21= 70
subsuits the values
7+14+21+28=70
70=70
