Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
While chatting in the school cafeteria, Cesar's friend Demi tells him that a new fantasy series was on Netflix and he should watch it. The new series has 12 seasons, and each season has 20 episodes. If Cesar watched 1/3 of the series before the school closed, how many episodes were remaining for him to finish the series?

### Response:
 Idadi jumla ya vipindi katika mfululizo ni vipindi 20 kwa msimu * misimu 12 = <<20*12=240>>240 vipindi.
Kabla shule haijafungwa, Cesar alitazama 1/3 ya mfululizo, ambayo ni 1/3 * 240 = <<240*1/3=80>>80 vipindi.
Idadi ya vipindi vilivyosalia kwa Cesar ili amalize mfululizo ni 240 - 80 = <<240-80=160>>160 vipindi.
