Abstract. Let $s,t,n$ be non-negative integers and $n\equiv 5\pmod{20}$. In this paper, we found that all non-negative integer solutions $(x,y,z)$ of the Diophantine equation $143^x+143^{2s}n^y=z^{2t}$ are in the following form:

\text{$(x,y,z)$}= \left\{
...lution} &\text{;}& \textrm{otherwise.} \\
\end{array} \right.
