hi! Im having trouble with this question about matrices

the matrix X =

(4 2)

(2 4)

X to the power of two =

2 (10 8 ) or

...(8 10)

4(5 4)

..(4 5)

X to the power of three =

2 (56 52)

...(52 56)

or 8 (14 13)

.......(13 14)

and so on...

I have to figure out an "pattern" so i can have a general formula for the scalar (which ive figured out) and the elements within the matrix.. which i cant seem to find... it has something to do with 3 to the power of n. Ive tried lots of combinations but none of them seem to fit.
