Find the third term of the geometric sequence when a1=1/4 and r=−2

Mathematics
1 answer:
Jobisdone [24]4 years ago
7 0

Answer:

1 is the third term.

Step-by-step explanation:

Geometric sequences have a common ratio.  This means a term divided by previous term is the same no matter the choosing of term.

So for example:

\frac{a_{n}}{a_{n-1}}=\frac{a_{n-1}}{a_{n-2}}=\cdots=\frac{a_4}{a_3}=\frac{a_3}{a_2}=\frac{a_2}{a_1}

So anyways geometric sequences means you are just multiply the common ratio over and over to generate the next term.

So, the first term is 1/4.

The second term is (-2)(1/4)=-1/2.

The third term is (-2)(-1/2)=1.

How do the values compare? Order the values from least to greatest.
aleksley [76]
Im pretty sure it would be ordered: -2 1/2, -1/2, |1/2|, 1 1/2, |-2|, |-2 1/2|

This is because
-1/2 stays as -1/2
the absolute value of |-2| is 2
the absolute value of |1/2| is 1/2
the absolute value of |-2 1/2| is 2 1/2
-2 1/2 stays as -2 1/2
and 1 1/2 stays the same as well.
If you take all these numbers (-1/2, 2, 1/2, 2 1/2, -2 1/2, and 1 1/2) and order them from least to greatest, you would get:
-2 1/2, -1/2, 1/2, 1 1/2, 2, 2 1/2
which is -2 1/2, -1/2, |1/2|, 1 1/2, |-2|, |-2 1/2|

Im not exactly sure if it is all correct, but i hope this helps! :)
