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

### Instruction:
A club is going to get additional members so that they will have 5 more than twice their current number of their members. If the club has 10 members now, how many additional members do they need?

### Response:
 Maradufu ya idadi ya sasa ya wanachama ni 10 * 2 = <<10*2=20>>20 wanachama.
Hivyo, klabu inataka kuwa na wanachama 20 + 5 = 25.
Hivyo, wanahitaji kupata wanachama 25 - 10 = <<25-10=15>>15.
