Answer:

  m = -6/7

Step-by-step explanation:

The sum of an infinite geometric series with first term a1 and common ratio r is ...

  S = a1/(1 -r)

Here we have the first term (3) and the sum (27/7) and we want to find r.

  27/7 = 3(1 -r)

  9/7 = 1 -r

  r = 1 -9/7 = -2/7

Then the value of m is 3r = 3(-2/7) = -6/7.
