3. In mathematics, Apry's constant is defined as the number 13,23,32,42 where is the Riemann zeta function. It has an approximate value of (3)-1.2020569031.... This constant arises naturally in a number of physical problems, including in the second- and third-order terms of the electron's gyromagnetic ratio using quantum electrodynamics. But, you don't need to know anything about that to solve this problem. Give a SCHEME function, named (apery k) that evaluates to an approximation for Apry's constant using k terms
