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)
