An arithmetic sequence is represented in the following table. Enter the missing term of the sequence.
[X] 1 | 2 | 3 | 4 | 35
[Y] -33 | -26 | -19 | -12 | ?

Missing term?

Answer 1

We are adding 7 each time.

The formula for an arithmetic sequence is

first term+(n-1)d

Where n is the number of terms, and d is the common difference

In this case, n is 35 and d is 7

Plug the numbers into the formula and you get

-33+(35-1)7

Solve

-33+(238)= 205
