The pattern goes

square, add 2, subtract 1,
square, add 2, subtract 1,
square, add 2, subtract 1,
etc., etc., etc.

Start with      1

Square 1, get   1
add 2, get      3
subtract 1, get 2

Square 2, get   4
add 2, get      6
subtract 1, get 5

Square 5, get   25
add 2, get      27     <--- that's the answer!
subtract 1, get 26

Square 26, get  676
add 2, get      678
subtract 1, get 677
