Nick observed how Mr. Gatsby strangely held out his arms toward the sea and seems to want to be alone.

Explanation:

F. Scott Fitzgerald's "The Great Gatsby" revolves around the story of the protagonist Jay Gatsby and his desire to be reunited with his former lover Daisy Buchanan. Though narrated by Nick Carraway, the story deals majorly with Jay Gatsby and delves into themes of love, fidelity, wealth, and society among others.

In Chapter 1, Nick recalls how he first saw a glimpse of his neighbor, Jay Gatsby. But even though he wanted to call out to his neighbor, Nick did not because it seemed like Mr. Gatsby wanted to be alone. Nick recalls how Mr. Gatsby "gave a sudden intimation that he was content to be alone—he stretched out his arms toward the dark water in a curious way". This made Nick not call out to him.
