If the 2nd term is 3 and the 5th term is 13, what is the 40th term

The difference between the 5th and 2nd term of an arithmetic series is 3 common differences so (13-3)/3=10/3.

If the 2nd term is 3 then the first term is 3-10/3=-1/3.

The nth term is -1/3+10/3(n-1). The 40th term is -1/3+130=129⅔

Step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

noncoplanar points are points that do not lie on the same line.
