This is a sequence defined Recursively:
an = ( an-1 - 1)2 ; a3 = 64
This means that every term, an , is equal to the preceding
term, an-1, minus 1 and that quantity squared
a1 = ( a0 -1 )2
a2 = ( a1 -1 )2
a3 = ( a2 - 1)2
64 = ( a2 - 1 )2 take square root of both sides
8 = a2 - 1
9 = a2
Do this same procedure to solve for a1
a1 = 4
