Question

Find the 94th term of the arithmetic sequence -26, -37, -48

Answer 1

-1049

Explanation:

Let's assume it's a arithmetic sequence

a_1 = -26

d = a_2-a_1 = -11

==> a_94 = a_1+93*d = -1049

Answer 2

-1071

Explanation:

Let the common difference be 'd'.

d is 11

Find the difference from a (first term) and 11

Then use (n-1)
