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

### Instruction:
One of Robi's new year's resolutions is to start saving. He started to save $2 in January. This is followed by $4 in February and $8 in March. If he continues this saving pattern, how much will be his total savings after 6 months?

### Response:
 Robi anaokoa $2 x 2 = $<<2*2=4>>4 mwezi wa Januari na Februari.
Ataweza kuweka akiba ya $8 x 2 = $<<8*2=16>>16 mwezi wa Aprili na Mei.
Ataweza kuweka akiba ya $16 x 2 = $<<16*2=32>>32 mwezi wa Juni na Julai.
Na ataweza kuweka akiba ya $32 x 2 = $<<32*2=64>>64 mwezi wa Agosti na Septemba.
Hivyo, akiba yake ya jumla baada ya miezi 6 ni $2 + $4 + $8 + $16 + $32 + $64 = $<<2+4+8+16+32+64=126>>126.
