Answer:
5th of this geomatic sequence are -20, -10, -5, -2.5 and -1.25
Step-by-step explanation:
I. Given geo sequence = output = a [tex]r^{n-1}[/tex], when a is 1st term, r is growth factor and n is term.
Find 1st value, 2nd , 3rd, 4th and 5th
1st term = -20
2nd term = -20 ([tex]0.5^{2-1}[/tex])
= -20(0.5)
2nd term = -10
3rd term = -20(0.5)^2 = -5
4th term = -20(0.5)^3 = -2.5
5th term = -20(0.5)^4 = -1.25
You can find any value with this solution, just replace x term in n value.
Hope that help :)
