Answer:
1. |r| = 1/4. or 0.25
2. Since r < 1, the geometric series is convergent.
3. To obtain the sum, we consider the formula of obtaining the sum to infinity of a geometrical series;
S = a /(1 - r)
where a = 2 ( first term)
r = 0.25 ( common ratio)
Therefore:
S = 2 /( 1 - 0.25)
= 2 / 0.75
= 8/3 or 2.6667
Hence, the sum is 8/3
2 1/3 does not involve radicals. Did you perhaps mean 2^(1/3)? If so,
2^(1/3) = ∛2

Step-by-step explanation:
2.7 gallons.
Since the tank is already 4/5 full, only 1/5 is needed to fill it completely. As 13.5 gallons represent 5/5 (the full tank), you can take 13.5 divided by 5 to find 1/5.
