\[\sum_{n=1}^{\infty} (-1/2 )^{n-2}\]
anonymous
  • anonymous
Okay, this is an infinite solution since the top is your upper limit and the bottom is the lower limit
anonymous
  • anonymous
so, -1/2^1-2 and so on - all the way to infinity - is going to be your answer

\[\sum_{n=1}^{\infty} 3(0.4)^{n-1}\]

that also and thanks keep explaining

1. -1/2^1-2 all the way to infinity (my answer for number 1?)
anonymous
  • anonymous
Same thing for this equation. Replace the n with the lower limit (1) all the way to infinity. You don't have to show the work up to infinity, just lead up to it
anonymous
  • anonymous
@Ket-kat so what would that be for number 2?
anonymous
  • anonymous
?
anonymous
  • anonymous
@Ket-kat whats the answer for 1 and 2, i'm confused.
anonymous
  • anonymous
hate that stuff
anonymous
  • anonymous
@15Trev can you still help me though?
anonymous
  • anonymous
Okay Like I said. In both equations on the left side of the stigma, replace the n with: 1,2,3,4,5,6,7,8,9,10.......... infinity And solve the equations :)

  • anonymous
i think so

Nice so its fresh for you
anonymous
  • anonymous
k
anonymous
  • anonymous
so first u have to know that whats in parenths is ur rate
anonymous
  • anonymous
multiply parenths by # next to them
anonymous
  • anonymous
1. \[\sum_{n=1}^{\infty} (-1/2)^{n-1}\] 2. \[\sum_{n=1}^{\infty} 3(0.4)^{n-1}\]
anonymous
  • anonymous
like 3x.4
anonymous
  • anonymous
=12
anonymous
  • anonymous
no
anonymous
  • anonymous
.4
anonymous
  • anonymous
3x.4= 1.2 my bad
anonymous
  • anonymous
ya
anonymous
  • anonymous
now take 1 and subtract by # in ( )
anonymous
  • anonymous
like 1-.4
anonymous
  • anonymous
.6
anonymous
