Answer:
You need to add more context to the question. I cannot answer it without knowing what "These scales" are.
ANSWER
Explicit formula:
Recursive
EXPLANATION
The first term of the sequence is
The common difference is
The nth term is given by the formula,
The explicit formula is;
The recursive definition is
An = 2n + 2
a1 = 2(1) + 2 = 2 + 2 = 4
a2 = 2(2) + 2 = 4 + 2 = 6
a3 = 2(3) + 2 = 6 + 2 = 8
a4 = 2(4) + 2 = 8 + 2 = 10
a5 = 2(5) + 2 = 10 + 2 = 12
1.3 would be considered greater than negative 5. Although 1.3 is a decimal it is still a positive number and positives are worth more than negatives regardless
