Determine if the sequence below is arithmetic or geometric and determine the common difference/ratio in simplest form.
Nana76 [90]

Step-by-step explanation:

this is clearly not a linear sequence (the terms don't have the same difference).

so, it has to be a geometric sequence.

the common ratio is r.

s2 = s1 × r

16 = 64 × r

r = 16/64 = 1/4

control :

s3 = s2×r

4 = 16 × 1/4 = 4

correct.

Solve for k, m = 3kx/7 - 9
kap26 [50]

Answer:

(7m + 63)/3x = k

Step-by-step explanation:

<em>m=3kx/7 - 9</em>

<u><em>add 9 to both sides:</em></u>

m+ 9 = 3kx/7

<u><em>multiply both sides by 7:</em></u>

7(m+9) = 3kx

<u><em>distribute the 7:</em></u>

7m+63 = 3kx

<u><em>divide both sides by 3x:</em></u>

<u>(7m + 63)/3x = k</u>
