Ball will bounce 83.9 meters high on the 8th bounce.
Geometric sequence:
- nth term of a geometric sequence is given by the expression,
[tex]T_n=ar^{n-1}[/tex]
Here, [tex]a=[/tex] First term
[tex]r=[/tex] Common ratio in each term
[tex]n=[/tex] Number of term
From the table attached,
- First term [tex]a=400[/tex] meters
- Common ratio [tex]r=\frac{\text{Second term}}{\text{First term}}[/tex]
[tex]=\frac{320}{400}[/tex]
[tex]=0.8[/tex]
8th term of the sequence will be,
[tex]T_8=400(0.8)^{8-1}[/tex]
[tex]T_8=83.886[/tex]
[tex]\approx 83.9[/tex] meters
