You have to use the equation 115h+35h=3125 and substitute until you find the answer. I'll try and figure it out while I'm eating and comment again

Find the explicit formula for the geometric sequence cn given below. Note that c1=6.
kodGreya [7K]

The explicit formula for the geometric sequence c_{n} is

c_{n}=6(\frac{-1}{3})^{n-1}

Step-by-step explanation:

The formula of the nth term of a geometric sequence is

a_{n}=a(r)^{n-1} , where:

  • a is the first term of the sequence
  • r is the common ratio between the consecutive terms

The geometric sequence of c_{n} is 6 , -2 , \frac{2}{3} , \frac{-2}{9} , \frac{2}{27}

∵ c_{1} = 6

∵ r=\frac{c_{2}}{c_{1}}

∵ c_{2} = -2

∴ r=\frac{-2}{6}

- Divide both term by 2 to simplify it

∴ r=\frac{-1}{3}

∵ c_{n}=c_{1}(r)^{n-1}

- Substitute the value of c_{1} and r in the rule above

∴ c_{n}=6(\frac{-1}{3})^{n-1}

The explicit formula for the geometric sequence c_{n} is

c_{n}=6(\frac{-1}{3})^{n-1}
