Step-by-step explanation:

the n number of value of x

let it be

now, the A.M of x is

since every value equal to a

substitute:

reduce fraction:

the G.M of x is

since every value equal to a

substitute:

recall law of exponent:

recall law of exponent:

the H.M of x is

since every value equal to a

substitute:

simplify complex fraction:

so

hence,

salary
