Question 666113
Let x be the first number.
Similarly, x+2 and x+4 are the next consecutive even numbers.

Sum of twice the first number and the third number is 30 more than the second would be:

2(x) + x+4 = x+2 + 30


2x + x + 4 = x + 32

3x + 4 = x + 32

2x = 28

x = 14

So, the numbers are 14,16,18.
