Geometric Series is known to be the exact sum of the terms of a geometric sequence. Its practice work example is given below:

Find the stated term of Given of the Geometric sequence -3, -6, -12, -24 ...9th term.

<h3>What is Geometric Means?</h3>

This is known to be the terms that exist between two nonconsecutive terms that belongs to a geometric sequence.

The Method to used in the above question is Geometric sequence.

The Rule of geometric sequence is that f (n)arⁿ⁻¹

Where A = the first term,

r = the common ratio

Therefore, r = -6 ÷ -3 = 2n

f (n) = -3. 2ⁿ⁻¹

Then you change the term n with 9

f (9) = 3.2⁹⁻¹

= -768

Therefore, the the stated term is 768.
