Amissing fraction on a number line is located exactly halfway between 3/6 and 5/6. what is the missing fraction

the answer is c

hope this !

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
