289 (i think)

Explanation:

i noticed that all of your numbers after the equal sign are squares so i squared them all and wrote the numbers down. i now have this sequence:

#3, 5, 5, 8, 11, 11 & 13#

it can be also written as:

#a b b c d d e#

where a+2=b and c+3=d. e+4 is the next step in this pattern. #17^2 = 289#
