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

### Instruction:
A papaya tree will grow 2 feet in the first year.  In the second year, it will grow 50% more than the first year.  In the third year, the tree will grow 50% more than in the second year.  In the fourth year, it will grow twice as much as the third year.  In the fifth year, it will grow half as much as the fourth year.  When the tree is 5 years old, how tall is the tree?

### Response:
 Katika mwaka wa pili, mti wa papai utakua 2 futi * 1.50 = <<2*1.50=3>>3 futi.
Katika mwaka wa tatu, utakua 3 futi *1.50 = <<3*1.50=4.50>>4.50 futi.
Katika mwaka wa nne, utakua 4.50 futi * 2 = <<4.50*2=9>>9 futi.
Katika mwaka wa tano, utakua 9 futi * 0.50 = <<9*0.50=4.50>>4.50 futi.
Mti ukiwa na umri wa miaka 5, ikiwa tunajumlisha ukuaji wa mwaka wa kwanza, utakuwa na urefu wa 2 + 3 + 4.50 + 9 + 4.50 = 23 futi.
