Part 1: Create a scenario for an arithmetic sequence. For example, Jasmine practices the piano for ______ minutes on Monday. Every day she ___________ her practice time by _________. If she continues this pattern, how many minutes will she practice on the 7th day? Be sure to fill in the blanks with the words that will create an arithmetic sequence. Use your scenario to write the function for the 7th term in your sequence using sequence notation. I need help learning how to solve this problem I don't get it just step by step on how

The first thing you have to do is pick numbers for the blanks.
anonymous
  • anonymous
@peachpi do I just pick any numbers
anonymous
  • anonymous
yes and for the 2nd blank decide whether you want it to increase or decrease

Ok so if I say she practices piano for 10 on Monday and increases by 5 min everyday
anonymous
  • anonymous
ok. so now you can write the formula for the sequence. \[a_n=a_1+d(n-1)\] \(a_1\)=10 because that was how much she practiced on the first day d = 5 because that's how much it increases each day. Plug them in to get the formula for you specific numbers
anonymous
  • anonymous
did you get a formula?
anonymous
  • anonymous
No how do I plug it in
anonymous
  • anonymous
Oh never mind I see I'll write it down
anonymous
  • anonymous
So an stays blank
anonymous
  • anonymous
right. both an & n don't change for this step
anonymous
  • anonymous
Ok I got an=15+5n
anonymous
  • anonymous
So or idk how to write the a and the n the way u did my bad
anonymous
  • anonymous
an = a1 + d(n-1) an = 10 + 5(n - 1) an = 10 + 5n - 5 an = 5n + 5 I think you may have added wrong somewhere
anonymous
  • anonymous
Now for the last step you plug in 7 for n to find \(a_7\). \[a_7=5(7)+5\]
anonymous
  • anonymous
I added the 5 to the 10
anonymous
  • anonymous
ok. That was it. It was supposed to be -5 added to the 10
anonymous
  • anonymous
So would it be 15 + 5n or no
anonymous
  • anonymous
It's 5 + 5n
anonymous
  • anonymous
Ok I got a7=40
anonymous
  • anonymous
that's right :)
anonymous
  • anonymous
Wait so that's it
anonymous
  • anonymous
yes
anonymous
  • anonymous
Omg thank you so much could you help me with another if you can it's the same but with a geometric sequence
anonymous
  • anonymous
yeah. just post another question and tag me
