Hints
(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A140893 a(n) = prime(n)^prime(n+1)-prime(n+1)^prime(n). 1

LINKS

Table of n, a(n) for n=1..9.

EXAMPLE

If n=1, then a(1)=prime(1)^prime(1+1) - prime(1+1)^prime(1)=2^3-3^2=8-9=-1

If n=3, then a(3)=prime(3)^prime(4) - prime(4)^prime(3)=5^7-7^5=78125-16807= 61318
