Transitions are messed up so a little explanation,
every other state on seeing a will goto $Q_1$
every other state on seeing b will goto $Q_2$
every other state on seeing c will goto $Q_3$
every other state on seeing a will goto $Q_4$
from these states if again that symbol is seen then goto Trap state ($Q_5$).
$Q_0$ is initital state
$Q_1 , Q_2 , Q_3, Q_4$ are final states
$Q_5$ is trap state
