Question

Write an explicit formula to represent:
3,5,7,9....

Answer 1

Answer:

a(n) = 3 + 2(n + 1)

Step-by-step explanation:

Hi, jacob,

Each new term here is obtained from the previous one by adding 2.  Thus the "common difference" is 2 and the explicit formula for a(n) is

a(n) = 3 + 2(n + 1)
