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

### Instruction:
A group of nine turtles sat on a log.  Two less than three times the original number of turtles climbed onto the log with the original group, creating an even larger group on the log.  Suddenly, half of the large group of turtles were frightened by a sound and jumped off of the log and ran away.  How many turtles remained on the log?

### Response:
 Wawili chini ya mara tatu ya idadi ya awali ya kobe ni (9*3)-2=<<9*3-2=25>>25.
Hivyo, Kundi la kobe 25 + 9 = <<25+9=34>>34 waliketi kwenye kigogo.
Lakini nusu ya kobe hawa walikimbia, hivyo kobe 17 walibaki kwenye kigogo.
