The following list gives the first 4 values of a sequence that follows a numerical pattern. 1,-4,-9,-14...

Which is most likely the 10th value in the sequence?

A) -36
B) -39
C) -42
D) -44

d. -44

Explanation:
Step 1 - Find the pattern

1, -4, -9, -14...

Clearly the pattern is adding negative five each time.

Step 2 - Simply continue the pattern until you get to the tenth value

1, -4, -9, -14, -19, -24, -29, -34, -39, -44

Therefore, the tenth value in the sequence is most likely -44.
