It's 5.
1/2 can also be written as 4/8.
So, it's 3 and 4/8 plus 1 and 4/8.
× =< 11\2

The right anser is A: 0.1395 because you multiply the two possibilities.
The numbers are: n, (n+2) and (n+4);
we can suggest this inequation:
84<n+(n+2)+(n+4)<96
Now, we solve this inequation:
84<n+(n+2)+(n+4)<96
84<3n+6<96
1)
3n+6>84
3n+6-6>84-6
3n>78
3n/3>78/3
n>26
2)
3n+6<96
3n+6-6<96-6
3n<90
3n/3<90/3
n<30
The solution is:
26<n<30
Then: n=28
The numbers will be: 28,30 and 32.
