 Given a geometric sequence with an even number of terms, where the sum of the even-numbered terms is twice the sum of the odd-numbered terms, the first term is 1, and the sum of the two middle terms is 24, find the total number of terms in the sequence. Express your answer as a whole number. Show your work in <think> </think> tags. And return the final answer in <answer> </answer> tags.<|im_end|>
