On Aircraft X to ZZZ at around XA:00 local time in our descent we received an EGPWS 'Terrain terrain; pull up pull up'. From 3;500 ft. on downwind CA (Captain) [Name] asked me to bug 2;500 ft. on the altitude knob. As we were descending I had mentioned to him that it looked like there may be rising terrain ahead of us. Continuing down to 2;500 ft. shortly after we were given the EGPWS audio to pull up. CA [Name] then clicked auto pilot off; added power and pitched up clearing any terrain that lie below us. The rest of the approach proceeded with no other complications. We had debriefed after engine shutdown at the gate. Looking forward I feel that my actions in this case would be to maybe be more assertive with my thoughts on the possible rising terrain in front of us and suggest to wait to descend until a base turn.
First Officer reported a lack of assertiveness caused the flying pilot to descend in rising terrain; triggering EGPWS warnings and an autopilot disconnect to regain altitude.
