Answer:
10,12,14
Step-by-step explanation:
Two consecutive integers will have difference of 2.
Let 3 consecutive even integers be a-2, a, a+2
Smallest number = a-2 and middle number = a
Sum of the smallest number and twice the middle number
= a-2+2a =3a-2
20 more than the largest number = 20+a+2 =a+22
i.e. 3a-2 = a+22
2a = 24
Or a =12
Hence three integers even consecutive are 12-2, 12, 12+2
=10,12,14
