Set up the system of equations and then solve it by using inverse matrices.
Bee ancestry Because a female bee comes from a fertilized egg and a male bee comes from an unfertilized egg, the number of ancestors of a male t + 2 bee generations before the present generation is the sum of the number of ancestors t and t + 1 generations
before the present. If the numbers of ancestors of a male bee in a given generation t and in the previous generation are given by
, then there is a matrix M such that the numbers of ancestors in the two generations preceding generation t are given by
.
For a given male bee, the numbers of ancestors 5 and 6 generations back are given by .
Find the numbers of ancestors 4 and 5 generations back by multiplying both sides of by the inverse of M.
