Let, a1 = 1, a2 = 2, b1 = 0, b2 = 1, for n 2 3, 2an-1 + bn-1 for n 22 b, = bn-1 +an-1 an express an in terms of n.

2. Let A - [1 0 3 2 3 4 02 Find A -1 if possible. If A-¹ does not exist, explain why.

In P2, find all real numbers a such that x - ax +1-a? is in the span of x -2x+1, x-1,and3x -2x-1. Oa = -2 or a =1 O a = -1 or 2 a can be any real number Oa = -2 or a=2 a =0
