What is the pka at half-equivalence

At half equivalence 12.65 mL of 0.0395 NaOH is titrated with a10.00mL of a weak acid of unknown concentration. The titration reaches equivalence once 25.3 mL of NaOH have been added. The initial and equivalence pH's are 3.105 and 8.991 respectively. What is the pKa at half-equivalence?
