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

### Instruction:
On Black Friday a popular electronics store sells 327 televisions. This is 50 more than they sold last Black Friday. If this sales trend continues and they sell 50 more televisions each year for three years, how many televisions will they sell on Black Friday three years from now?

### Response:
 Mwaka wa kwanza watauza televisheni 327 + 50 = <<327+50=377>>377.
Mwaka wa pili watauza televisheni 377 + 50 = <<377+50=427>>427.
Mwaka wa tatu watauza televisheni 427 + 50 = <<427+50=477>>477.
