Define arithmetic sequences.
A sequence whose terms change by adding the same number each time.
A sequence whose terms change by multiplying the same number each time.
A sequence whose terms change by dividing the same number each time.
A list of numbers that often (but not always) form a pattern.
Define common difference.
the product between two consecutive terms of a geometric sequence.

3, 7, 11, 15, ...
Write the explicit formula for the sequence.
9, 5, 1, -3, ...
an=9+5(n−1)
an=9−4(n−1)
an=4+9(n−1)
an=9⋅4(n−1)
-23, -16, -9, -2, ...
an = -23 + 7(n -1)
an = -23 - 7(n -1)
an = 7 - 23(n -1)
an = 7 + 23(n -1)
-5, -2, 1, 4, ...
a1 = 3 and d = -5
a1 = -8 and d = 3
a1 = -5 and d = 3
a1 = -5 and d = -3
What is the explicit formula?
5, -3, -11, -19, ...
an = 5 + −6(n−1)
an=5 + −8(n−1)
an=5 + 6(n−1)
an=11 + 6(n−1)
What is the explicit formula?
2, 11, 20, 29, ...
an = −5+ −7(n−1)
an=2+ −7(n−1)
an=2 + 7(n−1)
an=2 + 9(n−1)
Use the Function Rule to determine the 27th term in the given sequence.
-5, -7, -9, -11, ...
-59
-57
-132
-137
Is the sequence arithmetic? If so, state the common difference.
35, 40, 50, 55, ...
no
yes, common difference = 5
