I have my math final tomorrow and I don't remember the quick method to finding the r value when they are not consecutive terms, please help me. n1=1/81, n3=1/3

No. An 'arithmetic' sequence is defined as one with a common difference.A sequence with a common ratio is a geometricone.
The ratio of 5 to 4 in lowest terms is simply 5:4. This ratio cannot be simplified further because 5 and 4 do not have any common factors other than 1. In mathematical terms, this means the ratio is already in its simplest form.
It means a ratio from which all common factors have been removed: in much the same way as a fraction may be simplified.
1 to 4
The ratio of successive terms in the Fibonacci sequence approaches the Golden ratio as the number of terms increases.
