Question

Solve this Algebra problem please, I can't figure it out.

Answer 1

• 
  `45927/4096`

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`
