What is the ninth term of the arithmetic sequence a(n) = -14 + (n - 1)(2)
Solution:
Given an arithmetic sequence:
a(n) = -14 + (n - 1)(2)
When n = 9
a(9) = -14 + (9 - 1)(2)
a(9) = -14 + 8(2)
a(9) = -14 +16
a(9) = 2
The ninth term in the sequence is 2.
What is the ninth term of the arithmetic sequence a(n) = -14 + (n - 1)(2)
Summary:
The ninth term of the arithmetic sequence a(n) = -14 + (n - 1)(2) is 2.
