" eal value of "x" such that "5^(1-x)+5^(1+x),a/2,25^(x)+25^(-x)" are three "

The least value of a for which 5^(1+x)+5^(1-x),a//2,25^(x)+25^(-x) are three consecutive terms of an A.P., is

The least value of a for which 5^(1+x)+5^(1-x),a//2,25^(x)+25^(-x) are three consecutive terms of an A.P., is

At what values of parameter a are there values of x such that the numbers: (5^(1+x)+5^(1-x)),(a)/(2),(25^(x)+25^(-x)) form an A.P.

If 5^(1+x) + 5^(1-x) , ( a)/(2), 25^(x) + 25^(-x) are in A.P., then the set of values of a for such an A.P. to exists is :

If x in R, the numbers 5^(1+x)+5^(1-x),(a)/(2),25^(x)+25^(-x) form an A.P. then a must lie in the interval

If x in R , the number 5^(1+x)+5^(1-x),a/2,25^x+25^-x form an AP , then a must lie in the interval
