Question

What is the 13th term of the arithmetic sequence? A. 3 B. 3 1/2 C. 4 D. 3 3/4

Answer 1

Here, a = 3/4, d = 1 - 3/4 = 1/4, n = 13
a(n) =  a + ( n - 1)d
a(n) = 3/4 + (13-1)1/4
a(n) = 3/4 + 12/4
a(n) = 3/4 + 3
a(n) = 15/4
a(n) = 3 3/4

In short, Your Answer would be Option D

Hope this helps!
