Let an = –3an-1 + 10an-2 with initial conditions a1 = 29 and a2 = –47. a) write the first 5 terms of the recurrence relation. b) solve this recurrence relation. show your reasoning. c) using the explicit formula you found in part b, evaluate a5. you must show that you are using the equation from part b.

We can express the recurrence,

in matrix form as

By substitution,

and continuing in this way we would find that

Diagonalizing the coefficient matrix gives us

which makes taking the -th power trivial:

So we have

and in particular,

can someone me: the midsegment through the legs of an isosceles triangle is 4 in. find the sides of the triangle if its perimeter is 20 in. ,   and point g is the centroid of the right △abc with hypotenuse ab=18 in. find cg.
