[00:01:06] hi i needed help with findin the common difference of each sequence
[00:01:18] i am soo confused on how to

ELIZABETH C (Tutor)
[00:01:36] ok. let's start at the beginning of the first sequence.
[00:01:41] difference means what?

[00:01:42] ok
[00:01:51] subtraction

ELIZABETH C (Tutor)
[00:02:21] good. to find the common difference subtract the first term from the second.

Guest (Customer)
[00:02:39] 7

ELIZABETH C (Tutor)

[00:03:06] now to double check yourself, if you add 7 each time, will you keep getting the next term?

Guest (Customer)
[00:06:24] if it a question asks you to determine whether each sequence is arithimitic
[00:06:43] does it mean if the next term is correct or what?

ELIZABETH C (Tutor)
[00:07:10] well, what makes a sequence "arithmetic"?

Guest (Customer)
[00:07:40] um im not sure??

ELIZABETH C (Tutor)
[00:08:13] ok. if there is a common difference or if we are adding the same thing each time to get the next term, if is arithmetic
