I came across a question about assembly that I was confused on.

We are given the following table for addresses and instructions: enter image description here

The question says: replace the labels of PC-relative targets with their immediate values. What is the offset value of bnez at address 0x20? Write your answer in decimal.

I put -6, since if bnez, it goes to loop, which is at 0x14. However, the answer given is -12.

How did they get that?
