+123 2. Create an arithmetic sequence up to 5 terms.
Then find the explicit formula for the nth term.
+36916 OK...we just get to make it up
Let's set a1 = 5
and d=3
a1 = 5
a2 = 5 +3 = 8
a3 = 5+3+3 = 11
a4 = 5 +3+3+3 =14
a5 = 5 +3+3+3+3 = 17
an = 5 + (3)(n-1)
Edited...... Thanx CPhill for pointing out I answered with a GEOMETRIC series rather than an Arithmetic series !!!
