Find the values of s1 and r for a geometric sequence with s4 = 18 and s6= 8

  see below

Step-by-step explanation:

The ratio of terms that are two terms apart (s4 and s6) is the square of the common ratio:

  s6/s4 = r^2

  r = √(8/18)

  r = 2/3 . . . . . matches choices A and C

Using the formula for the general term, we now know enough to find the first term:

  sn = s1·r^(n-1)

  s4 = s1·(2/3)^(4-1)

Using s4 = 18 and multiplying by (2/3)^-3, we get ...

  18·(2/3)^-3 = s1 = 18·27/8

  s1 = 243/4 . . . . . matches choice A

step-by-step explanation:

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7
