Answer 1

Find the 13th term in the following arithmetic sequence

2, 10, 18, 26 ...192 is the 13th term

Answer 2

a(13) = 98

Explanation:

a(n) = a1 + (n-1) d

a1 would be the original term, 2

since you are looking for the 13th term a(n) and n is 13

a(13) = 2 + (13-1) d

d would be the difference between each term, 8

a(13) = 2 + (13-1) 8

Now solve

a(13) = 2 + 12 * 8

a(13) = 2 + 96

a(13) = 98
