The sequence `{x_1, x_2,....x_(50)}` has the property that for each n,`x_n` is n less then sum of other 49 numbers then `x_(20)` is

The sequence {x_(1),x_(2),…x_(50)} has the property that for each k , x_(k) is k less than the sum of other 49 numbers. The value of 96x_(20) is

The sequence {x_(1),x_(2),…x_(50)} has the property that for each k , x_(k) is k less than the sum of other 49 numbers. The value of 96x_(20) is

A sequence x_1, x_2, x_3,.... is defined by letting x_1=2 and x_k=x_(k-1)/k for all natural numbers k,k>=2 Show that x_n=2/(n!) for all n in N .

The average of n numbers x_(1), x_(2), ….., x_(n) is M. If x_(n) is replaced by x', then new average is :

The sum of the deviations of a set of n values x_1, x_2 ,.........x_n measured from 50 is-10 and the sum of deviations of the values from 46 is 70.Find the values of n and the mean.

The sum of the deviations of a set of n values x_(1),x_(2),.......x_(n) measured from 50 is -10 and the sum of deviations of the values from 46 is 70. Find the values of n and the mean.
