Irrational

Step-by-step explanation:

x = ± $\sqrt{55}$ ← irrational

$\sqrt{55}$ cannot be expressed as a rational number

Answer:

$45927/4096$

Step-by-step explanation:

Given is the geometric series, because the ratio of consecutive terms is common:

$r = 84/112 = 63/84 = 3/4$

The first term is 112.

So the nth term is:

$t_n = t_1*r^{n-1}$

The 9th term is:

$t_9 = 112*(3/4)^8=45927/4096$
