A sequence which has a specific order Known as____
PATTERN
Is the sequence arithmetic, geometric, or neither?
6, 3, 0, -3, -6, ...
arithmetic
Formula in finding d in an arithmetic sequence.
a2 - a1
Using the sequence: 3, 7, 11, ...,what is the 5th term?
19
It is denoted by d
Common Difference
is the sequence arithmetic, geometric, or neither?
9, 36, 144, 576, 2304, ...
geometric
General formula in finding the sequence in an arithmetic sequence.
an = a1 + (n-1)d
Given the sequence: 6, 12, 24..., what is the common ratio?
r = 2
It is a sequence which has a common difference
Arithmetic Sequence
What type of sequence is:
1, 1, 2, 3, 5, 8, 13, 21, 54,...?
Fibonacci Sequence
Formula in finding Sn in an arithmetic sequence whose a1 and an are given.
Sn = n/2( a1 + an)
How many terms are there in a sequence if the last term is (-20), a1 = 5 and the common difference is (-5)?
n = 6
It is obtained by dividing the succeeding term to the preceding term.
common ratio
Is the sequence harmonic or not?
1/5, 1/9, 1/13, 1/17,....?
Harmonic
A geometric sequence starts
4, 16, ...
Write an explicit definition for it.
4n
Find the second geometric mean in a sequence:
4,___, ___, 108?
r = 3, therefore the second geometric mean is 36.
It is the sum of all the terms in an arithmetic sequence.
Arithmetic Series/sequence
Is the sequence arithmetic, geometric, or neither?
a1 = 8, a2 = 11, a3 = 16
neither
Write the general formula in the sequence:
2, 4, 8, 16,..
2n
What is the sum of the first 12 even numbers from 5 t0 29?
Sn = 204
