Am i correct for this math question

Step-by-step explanation:

Hammers and Wrenches

I have included the graph to the first one. C is the best answer, but I don't think it is quite correct, although it is true. The actual fact is that there is no y intercept as near as I can get. That's an unusual occurrence for this kind of graph. There is no other answer that will satisfy or rectify that condition. I think you are likely to answer C, but be careful. It could turn out to be another answer.

I agree with your answer

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

1 the 1st term, 3 the 2nd term, 6 the 3rd term,etc.

note the following:

from the 1st term (1) to the 2nd term (3), we go up by 2,from the 2nd term (3) to the 3rd term (6), we go up by 3from the 3rd term (6) to the 4th term (10), we go up by 4, andfrom the 4th term (10) to the 5th term (15), we go up by 5.

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
