It feels like the third term should be sixteen. ]]> 2021-10-27 16:12:49 UTC https://padlet.com/maciejflisak/42xvjpdhd6ibffw1/wish/1848767123 Where can the Sigma Notation button be found on the calculator? maciejflisak https://padlet.com/maciejflisak/42xvjpdhd6ibffw1/wish/1853305329 2021-10-29 06:23:23 UTC https://padlet.com/maciejflisak/42xvjpdhd6ibffw1/wish/1853305329 Recursive rule https://padlet.com/maciejflisak/42xvjpdhd6ibffw1/wish/1855512794 When you write a recursive rule does it have to include specifically U1 or can it just use a previous term? Would this be the recursive rule for a geometric sequence:
Un=U1 * r^n-1
or would you just call this a rule for finding Un?
Basically the question summed up is how do you define a recursive rule?]]> 2021-10-30 13:39:42 UTC https://padlet.com/maciejflisak/42xvjpdhd6ibffw1/wish/1855512794 Video 2 https://padlet.com/maciejflisak/42xvjpdhd6ibffw1/wish/1855854452 I think you made an error at 2:47...
Question d doesn't have a common ratio of 2x if you look at the third term compared to the second term. Am I wrong?]]> 2021-10-30 19:33:13 UTC https://padlet.com/maciejflisak/42xvjpdhd6ibffw1/wish/1855854452 Finding sigma notation https://padlet.com/maciejflisak/42xvjpdhd6ibffw1/wish/1856784849 I had a bit of trouble finding the sigma formula/equation for 2e in the bottom of the practise assignment. Is there a way you can generally find the sigma equations or formulas quickly because that was one of my struggles.]]> 2021-10-31 15:01:39 UTC https://padlet.com/maciejflisak/42xvjpdhd6ibffw1/wish/1856784849 Can r = 4 and r = -4 in this problem... ? maciejflisak https://padlet.com/maciejflisak/42xvjpdhd6ibffw1/wish/1861558746 2021-11-02 13:07:55 UTC https://padlet.com/maciejflisak/42xvjpdhd6ibffw1/wish/1861558746 Something doesn't work https://padlet.com/maciejflisak/42xvjpdhd6ibffw1/wish/1862603200 The problem we were talking about in video 1 at 14:39 didn't give the same result with the other formula you gave us...
I checked it a couple times but it didn't work.

In question 4 you ask us what exponent b would have if it was term 20, and then you go on to explain that the b's exponent value will be 1 less than its term number, therefore, if it was term 20 the number would have been 19, however, in the video you wrote the answer as 20...
