The first term of a geometric sequence is –2 and the common ratio is -1/4 . what are the next three terms of the sequence

Step-by-step explanation:

Given that the first term of a geometric sequence is -2 and the common ratio is -1/4.

we have to find the next three terms of the sequence.

The geometric sequence can be written as

where a and r are the first term and common ratio.

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
