Question

What is the 46th term in the arithmetic sequence? -1.5,-1.3, -1.1,-0.9...?

Answer 1

Answer:

a(46) = -1.5 + 0.2(45) = -1.5 + 9 = 7.5

Step-by-step explanation:

Each term of this sequence is 0.2 greater than the previous term.  The formula for this arithmetic sequence is

a(n) = -1.5 + 0.2(n - 1)

and so the 46th term is:

a(46) = -1.5 + 0.2(45) = -1.5 + 9 = 7.5
