why did captain Silver hated squire Trelawney ?

Squire Trealwney is the figure in the book who financially underwrites and initiates the treasure hunt. Although he appears to be on top of things, he often makes mistakes and his hiring of Long John Silver and the mutineers tops the list of misjudgments and miscalculations which lead to the downfall of the journey. He is very naïve and trusting, and, thus, is constantly being duped. Silver sees Trealwney as part of the elite establishment. He does not respect hi naivety or his instincts.
