There are four real numbers. The product of the first three arithmetical sequences is 216, and the sum of the last three arithmetical sequences is 24
Let these four numbers be A1, A2, A3, a4a1, A2, A3 be equal ratio sequence, A2, A3, A4 be equal difference sequence, A1 * A3 = A2 & # 178; A2 + A4 = 2a3a2 = 6, let the common ratio of equal ratio sequence be qs4 = a1 + A2 + a3 + A4 = a1 + 3a3 = (6 / Q) + 3 * 6q = 24q = 1 or q = 1 / 3Q = 1, when the four numbers are 6,6,6,6q = 1 / 3, the four numbers are 18,6,2, - 2
