a.
To explain: what makes a sequence arithmetic.
a.
Answer to Problem 81CR
Common difference makes a sequence arithmetic.
Explanation of Solution
Given information: A sequence
Calculation:
A sequence is a set of numbers, called terms, arranged in some particular order. An arithmetic sequence is a sequence with the difference between two consecutive terms constant. The difference is called the common difference.
If the sequence has a common difference, it's arithmetic.
For example 2,4,6,8,10 is a arithmetic sequence with common difference 2.
So, common difference makes a sequence arithmetic.
b.
To explain: what makes a sequence geometric.
b.
Answer to Problem 81CR
Common ratio makes a sequence geometric
Explanation of Solution
Given information: A sequence
Calculation:
A sequence is a set of numbers, called terms, arranged in some particular order. A geometric sequence is a sequence with the ratio between two consecutive terms constant. The ratio is called the common ratio.
If the sequence has a common ratio, it's geometric.
For example 2,4,8,16,32 is a geometric sequence with common ratio 2.
So, common ratio makes a sequence geometric.
