Consider the equation: x2 + 10x + 22 = 13
1) Rewrite the equation by completing the square.
Your equation should look like (2 + c)2 = d or (2 – c)2 = d.
2) What are the solutions to the equation?
Choose 1
x = 5+or- 4
x = -5 +or - 4
x = 5 + or - 16
x = -5 +or - 16

Asequence {an} is defined recursively, with a1 = 1, a2 = 2 and, for n > 2, an = an-1 an-2 . find the term a241
