Write the first four terms of the sequence.an = (-1)n+9
A. a1 = -1, a2 = 1, a3 = -1, a4 = 1 B. a1 = -1,a2 = -1, a3 = -1, a4 = -1 C. a1 = 1, a2 = 1, a3 = 1, a4 = 1 D. a1 = 1, a2 = -1, a3 = 1, a4 = -1
Solve the problem.Let a1 = 
, a2 = 
, and b = 
.Determine whether b can be written as a linear combination of a1 and a2. In other words, determine whether weights x1 and x2 exist, such that x1 a1 + x2 a2 = b. Determine the weights x1 and x2 if possible.
A. x1 = -1, x2 = -3 B. No solution C. x1 = -2, x2 = -2 D. x1 = -2, x2 = -1
