Question

For the following geometric sequence find the 5th term in the sequence.
{0.125, -0.25, 0.5, ...}

Answer 1

Hello there!

Answer:

2

Step-by-step explanation:

In order to find the 5th term in the sequence, you would need to find the number that multiplies to get the next number.

In this case, that number would be "-2"

The reason why it's "-2" is because when you multiply 0.125, you would get -0.25. And, when you multiply -0.25 by -2, you would get 0.5.

You would pretty much keep multiplying by 2 until you get the 5th term.

________________

0.125  ------> 1st term

× -2

-0.25 ------> 2nd term

× -2

0.50 ------> 3rd term

× -2

  -1   ------> 4th term

× -2

  2  ------> 5th term
