Multiple choice general knowledge 1, 4, 27, 16, Z, 36, 343 25 87 120 125 Reveal answer Fill a bubble to check yourself D Correct answer Explanation This is an alternating series: odd positions are n³ (1³=1, 3³=27, 5³=125, 7³=343) and even positions are n² (2²=4, 4²=16, 6²=36). So Z = 5³ = 125. The pattern uses cubes for odd terms and squares for even terms.
