For your info : 

(a)   a^n   means  a%5En,  and is used ONLY for this purpose: to show raising in degree "n".


      For example,  2^2 = 2%5E2 = 4;   3^2 = 3%5E2 = 9.



(b)   If you want to show the n-th term of a progression / (of a sequence), write  a[n]  or  a(n). 


      We, the tutors, will read it as  a%5Bn%5D.
