Let `alpha and beta` are the roots of `x^2 + 10x -7=0`. If `a_n=alpha^n +beta^n` for `n leq 1` then the value of `(a_12-7a_10)/(2a_11)` is

Let alpha and beta are the roots of x^(2)+10x-7=0. If a_(n)=alpha^(n)+beta^(n) for n<=1 then the value of (a_(12)-7a_(10))/(2a_(11)) is

Let alpha and beta be the roots of equation x^2-6x-2""=""0 . If a_n=alpha^n-beta^n ,""for""ngeq1 , then the value of (a_(10)-2a_8)/(2a_9) is equal to: (1) 6 (2)-6 (3) 3 (4) -3

alpha and beta are the roots of x^2-x-1=0 and S_n=2023 alpha^n 2024 beta^n then
