If a (n + 1) < an, A2 × A8 = 6, A4 + A6 = 5, then A5 / A7 is equal to______

If a (n + 1) < an, A2 × A8 = 6, A4 + A6 = 5, then A5 / A7 is equal to______


Let the common ratio be Q
A 4 a 6 = a 2 a 8 = 6, and a 4 + a 6 = 5. A 4 and a 6 are two parts of the equation x & # 178; - 5x + 6 = 0
(x-2)(x-3)=0
X = 2 or x = 3
a(n+1)



In the arithmetic sequence {an}, A3 = 10 and A3, a7, A10 are in the same ratio sequence, then what is the tolerance D equal to


(a7)^2=a3 * a10
(a3+4d)^2=a3*(a3+7d)
D = 0 or - 5 / 8
