What is a sequence in which a common difference separates terms?
arithmetic sequence
Is The Fibonacci sequence arithmetic?
No, the Fibonacci sequence is not an arithmetic because the difference between consecutive terms is not constant
What is the sum of the first ten terms of the arithmetic sequence 4 4.2 4.4...?
49
What is it where you find terms by adding the common difference to the previous terms?
An arithmetic sequence.
How do you use a arithmetic sequence to find the nth term?
The difference between successive terms in an arithmetic sequence is a constant. Denote this by r. Suppose the first term is a. Then the nth term, of the sequence is given by t(n) = (a-r) + n*r or a + (n-1)*r
What is the type of sequence where the terms in the sequence are found by adding the same number each time?
That's an arithmetic sequence.
What is a sequence in which a common difference separates terms?
arithmetic sequence
Is The Fibonacci sequence arithmetic?
No, the Fibonacci sequence is not an arithmetic because the difference between consecutive terms is not constant
Does the terms of an arithmetic sequence have a common ratio?
No. An 'arithmetic' sequence is defined as one with a common difference.A sequence with a common ratio is a geometricone.
Rule to finding terms in a arithmetic sequence?
The nth term of an arithmetic sequence = a + [(n - 1) X d]
How do you determine if a sequence is arithmetic?
The sequence is arithmetic if the difference between every two consecutive terms is always the same.
What is the sum of the first ten terms of the arithmetic sequence 4 4.2 4.4...?

A sequence in which the terms change by the same amount each time?
Arithmetic Sequence
What is it where you find terms by adding the common difference to the previous terms?
An arithmetic sequence.
A sequence in which the difference between any two consecutive terms is the same?
arithmetic sequence this is wrong
