Use the following table to answer questions.
x y
1 7
3 ?
? 11
7 13
? ?
What are the values of x and y in the last row of the table?
What is the rule for this table?

2 is added to the previous number.

not nearly enough information, since only two ordered pairs are given.
Is the relation linear? , then we could do it.
slope = (137)/(71) = 1
so y = x + 6
so the table would be:
1 7
3 9
5 11
7 13
? ? , your choice
however , as I implied there could be other rules
e.g. y = (1/6)(x1)^2 + 7 , also contains (1,7) and (7,13)
