Explanation:
First we have to write the given data in mathematical terms.
this would be 2n,2n+2 and 2n+4
So
2n+2n+2 tells us that it would be 30
so 4n+2=30
30-2=28 as +2-2 makes 0
4n=28
divide by 4
n=7
we have found n meaning we can substitute to the equations
so 2n=2*7 is 14
2n+2 is 2*7+2=16
2n+4 is 2*7+4 is 18
Therefore the three consecutive numbers are:
14,16 and 18
