Is this an arthimatic sequence ? 10,20,40,80

An arithmetic sequence has a common difference between each term in the series. A geometric sequence has a common ratio between each term in the series.

First, let's determine the rate of change between each term.

10, 20 = multiplied by 2

20, 40 = multiplied by 2

40, 80 = multiplied by 2

The terms appear to have a common ratio of 2, making this a geometric sequence. Therefore, this is NOT an arithmetic sequence.

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )

hi there, i would be interested to you with your test, may you add the questions and answer options.
