Question

Write the first ten terms of a sequence whose first term is -10 and whose common difference is -2.

Answer 1

Is this an arithmetic sequence or an arithmetic sequence ?

Answer 2

oops..or a geometric sequence

Answer 3

These is an arithmetic sequence

Answer 4

In an arithmetic sequence, you find the number by adding.
-10 + (-2) = -10 - 2 = -12 (1st term)
-12 + (-2) = -12 - 2 = -14 (2nd term)
-14 + (-2) = -14 - 2 = -16 (3rd term)

you get the idea ?

Answer 5

oops..-12 is the second term....and so on...

Answer 6

I think so I would just continue that pattern until the 10th term?

Answer 7

yes

Answer 8

So would the 10th term be -30?
