Answer:
Step-by-step explanation:
2n is an even number.
Your three even numbers are 2n, 2n + 2, 2n + 4
Twice the first is 20 more than the second.
2n * 2 = 2n + 2 + 20
Simplify:
4n = 2n + 22
Use simultaneous equations to solve n.
4n = 2n + 22 - 2n
2n = 22 ÷ 2
n = 11
Subsitiye n into the three even numbers.
2n, 2n + 2, 2n + 4
2 * 11, 2 * 11 + 2, 2 * 11 + 4
22, 24, 26
Check that the numbers meet the requirements.
22 * 2 = 24 +20
44 = 44
