Question

What is the 35th term of the arithmetic sequence where a1 = 13 and a17 = -35

Answer 1

I'm thinking its -83, but I'm not sure. Anyone help is appreciated.

Answer 2

so, what did you get the common ratio?

Answer 3

An = a + (n-1)d

Answer 4

between 13 and -35, there are 48 units of difference
48 units split between 16 elements, excluding the 1st term that is

it'd give use a common ratio of 3
it goes from positive to negative, thus the common ratio will be -3

Answer 5

so use that in the arithmetic sequence as shown by ivettef365 :)
