Lemur [1.5K]

Answer:

c = 2

Step-by-step explanation:

Since 16 is over the variable c, first multiply both sides by c so the variable is not in the denominator of the fraction.

16/c(c) = 8(c)

16 = 8c           Next, divide both sides by 8 to solve for c.

c = 2

7th term in geometric sequence an=2 5(n-1)
Soloha48 [4]
To find the 7th term, all you have to do is plug it in the equation.

First n would equal 7 because we are looking for the 7th term.

Now, let's plug everything we know into the equation.

a7 = 2+5 * (7-1)

= 2 + 5 * 6

= 2 + 30

= 32

In conclusion, the 7th term would equal 32.
