The tenth, eleventh, and twelfth terms of a sequence are shown in the table below: Term number 10 11 12 Term -34 -38 -42 Which of the following shows the first five terms of the sequence? -2, 2, 6, 10, 14 2, -2, -6, -10, -14 -2, -6, -10, -14, -18 2, 6, 10, 14, 18
holy crap thats hard
The terms are decreasing by 4 as the term position goes up. Do you agree? |dw:1443820971295:dw|
Yesss I do.
We need to start at -34 and ADD 4 to get the 9th term. We will add 4s and go backwards and count to the first term. |dw:1443821119010:dw|
Click on the pencil icon and fill in the values of each term beginning with term 7 all the way back to term 1. You will be adding 4 each time. Fill those in and then post and let's see what happens, okay?
Do you follow what I'm asking you to do?
Yes but how would I solve them with a negative number?
Can you give an idea of how to do it?
Start with -26 and add 4. Think of it as your owing me $26 and then giving me $4 to pay on the debt. If you did that how much would you still owe me?
|dw:1443832531228:dw| is this correct?
I think I messed up on the numbers order.
No. The 7th term is -26 + 4 = -22. The 6th term would then be -22 + 4 = -18 See if you can get the 5th term on down to the first term. |dw:1443821852902:dw|
oh okay so the sequence would be 2, -2, -6, -10, and -14 ???
2, -2, -6, -10, -14
oh okay, thanks.
You are welcome.
