Question: 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? Think carefully first, then make a decision:

Robi will save $8 x 2 = $16 in April. He will save $16 x 2 = $32 in May. He will save $32 x 2 = $64 in June. Hence, his total savings after 6 months will be $2 + $4 + $8 + $16 + $32 + $64 = $126. So the answer is 126.
