Question

Find the indicate term for each geometric series described.

Answer 1

\[Find :a _{1}\]\[r=-2\]\[s _{n}=33\]\[a _{n}=48\]

Answer 2

formula:\[s _{n}=\frac{a _{1*(1-r^n)}}{1-r}\]

Answer 3

48 - 24 + 12 - 6 + 3 = 33
so a1 = 3

Answer 4

How u get number 24,12,6,3?

Answer 5

u use r=-2
keep divi 2

Answer 6

It's a geometric series, therefore every term is going to be r times the next. You just go backwards and find the solution. If you start from 3, then multiply by -2, which is the rate, and you get -6, and so forth :)

Answer 7

Ok,I see TY
