The eighth term of the given geometric sequence is: 384.

What is a geometric progression?

  • A geometric progression, sometimes referred to as a geometric sequence in mathematics, is a series of non-zero numbers where each term following the first is obtained by multiplying the preceding one by a constant, non-zero value known as the common ratio.

Now, given: -3, 6, -12, ....

Here, [tex]\frac{6}{-3}=\frac{-12}{6} = -2[/tex]

Thus this geometric progression has the common ratio = -2.

The nth term of a geometric sequence is given by: [tex]a_n=a_1(r^{n-1})[/tex]

For n = 8, a₈ = a₁ ( r⁸⁻¹)

=> a₈ = (-3)(-2)⁷

=> a₈ = 3 ( 128) = 384.

Hence, The eighth term of the given geometric sequence is: 384.
