In the given sequence, <span>each subsequent term is the reciprocal of the square of the preceding term.
We know that the first term is 2, this means that the second term is: 1/(2)^2 which is 1/2 The third term in the sequence would be: 1/(1/4)^2 = 1/(1/16) = 16 The forth term in the sequence would be: 1/(16)^2 = 1/256 The fifth term in the sequence would be: 1/(1/256)^2 = 1/(1/65536) = 65536
Now, the question asks for the positive root of the 5th term, this means the positive root of 65536 which is 256</span>
