Explanation

The pattern is: 25 * 2 + 2 = 52, 52 * 2 + 4 = 108, 108 * 2 + 8 = 224, 224 * 2 + 16 = 464. Following this, the next term is 464 * 2 + 32 = 928 + 32 = 960.

AI explanation

Each number in the series is generated by doubling the previous number and adding a decreasing even number: +2, +4, +8, +16, and +32. To find the missing term, we double 464 to get 928 and add 32, which results in 960. This logic holds for the next term as well, since 960 times 2 plus 64 equals 1984.
