Which is true regarding the sequence below?

5,2,-3,-10,-19

a. the sequence is arithmetic because the common difference is -1.
b. the sequence is arithmetic because the common difference is 1.
c. the sequence is not arithmetic because there is no common difference. the differences are -3,-5,-7 and-9.
d. the sequence is not arithmetic because there is no common difference. the differences are -1/3,-1/5,-1/7 and -1/9

Option C is correct.The sequence is not arithmetic because there is no common difference. The differences are -3,-5,-7 and-9.

Step-by-step explanation:

We have given the sequence 5,2,-3,-10,-19

Common difference of arithmetic sequence is

we can see the difference between all the terms are d=2-5=-3  here

 here

 here

 here

Therefore, this is not an arithmetic  because there is no common difference.Differences are -3,-5,-7 and-9.

i think it would be 42cm

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.
