What is the 20th term for the sequence of 0.125, -0.250, and 0.500

20th term -65536

Step-by-step explanation:

sequence is:

0.125, -0.250, 0.500,

Because 0.125 is the first term we can find it easy

the factor found for the sequence is (x(-2)). multiplied by negative 2.

so:

0.125 x (-2) = -0.250

-0.250 x (-2) = 0.500

you can find the term number 20 from the 1st term. So really you are looking for term 19 because you allready got the first one.

insted of doing one by one that it will work you can skip by:

0.125*(-2)^(19)      to the 19th term caose 0.125 is the first one.

0.125*(-2)^(19) = -65536
