The answer is 8. You rewrite the fraction as 5.25.
Answer:
1/2
Step-by-step explanation:
Since the recessive gene is carried in the x chromosome and a father can only pass it to a daughter, the father doesn't have the disease nor carries it.
The mother carries the recessive gene because her father passed her his conditioned gene (only having one x chromosome), while her mother gave her a normal one so she can have normal vision.
The chance of having a boy or a girl is 1/2 and the chance of this baby of having both recessive gene is null because in order to have a girl that is color blind both her x chromosomes must have the recessive gene, but the father can't pass it since he doesn't carries it. Therefore the combined probability is 1/2*(1-0) = 1/2.

Step-by-step explanation:
I'm guessing you want to fill in the blanks of the sequence?
We can represent this as an equation:
31-3x=18
-3x=13
x=-13/3
Second term: 31 - (13/3) = 26 2/3
Third term: 26 2/3 - (13/3) = 22 1/3
