1. 1.1 Cont. Give the first 4 terms of the sequence: a. b. Warm-up (IN)
Learning Objective: to continue to find terms of sequences and then to find the sum of an arithmetic series
Warm-up (IN)
Give the first 4 terms of the sequence: a. b.
2. Write a rule for the nth term of the sequence: 6, 1, -4, -9, …
5, -2, -9, -16
-2, 8, 18, 28

2. Notes!
Ex 1 – if find
Ex 2 – find for 5, 11, 17, 23, …

3. First we need to find d
Ex 3 – find if and
Pretend…
then…
also…
or…

4. Ex 4 – find the missing numbers in the arithmetic sequence
2, ____, ____, ____, 18
First we need to find d
Arithmetic Series –
The expression formed by adding the terms of an arithmetic sequence
We can only find the sum if the series is finite 30 30
30x3
=90 30

5. Sum formula – Ex 5 – find 7+5+3+1+-1+-3+-5
W2L – the difference between a sequence and a series is…
Ex 5 – find
Ex 6 – find …+42
First we need to find n

6. First we need to find the last term
Ex 7 – find if
