Sequences: A sequence is a list of numbers that is separated by columns.Arithmetic Sequence: List of # called terms which share a common difference.
4,14,24,34 - 1,2,4,7,11- 3,-147,-297,-447- 10,8,12,10,14
The second one is not an arithmetic sequence. Even with a pattern the terms in this sequence. The difference between each of the terms isn't consistent.
Today we will be discussing arithmetic sequences and series. To start this lesson we have 4 different sequences listed on the board and I want you to discuss whether the sequences are arithmetic or non arithmetic.
The first one is an arithmetic sequence. Each of the terms are separated by a common difference of 10.

The 3rd is an arithmetic sequence. The terms are separated by a common difference of -150.
All of your answers and reasoning's were correct! Tonight's homework you will need to find the _ term in an arithmetic sequence
The last one isn't an arithmetic sequence. The difference between each of the terms is not consistent even though there is a pattern.

Now I need to substitute the values into the formula. A29=11+(29-1)(-3). I will show the rest of my work on the computer.
a29=11+(28)(-3)a29=11+(-84)a29=-73The 29th term is -73
