The ratio between consecutive terms of a geometric sequence.

x:x+1

Step-by-step explanation:

consecutive terms just mean numbers greater or lower by one; whole number im assuming. so make the number x and have x+1 for the next one.

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
