The given question is asking for the sum of the numbers in the series. The series starts with 32 and each subsequent number is multiplied by 2. Therefore, the next number in the series would be 64, then 128, and so on. The sum of the series is obtained by adding all the numbers together, which would be 32 + 64 + 128 + 256 = 480. Therefore, the answer of 160 is incorrect.
