Araujo scored the Barça equaliser, cancelling out Papu Gomez's opener, but Xavi Hernandez's side couldn't go on to win the game despite playing against 10 men for the final half an hour after Jules Kounde's red card.
"We've taken a step forward," Araujo told Movistar. "We played well against a difficult side in Sevilla. We deserved more because we were better in the second half.
"There were good spells in the first half, too, so it's a shame we switched off a little for their goal. We're on the right path."
Ousmane Dembele hit the post late on and Jordi Alba, Gavi and Luuk de Jong also had chances but Barça once again paid for failing to take their chances.
"We're working on that [scoring more]," Araujo added. "There are young players like Ferran [Jutgla] who are doing a great job. We're a bit short of goals to kill these games off. We're working on it and hope to correct it in the second half of the season."
