You may have read or heard that the ideal paragraph consists of one thought. Clearly, there are various ways to begin and end a thought. One way is to start with a claim or topic sentence, offer examples for your claim, explain how your examples support the claim, repeat the claim in the light of the examples, and build a bridge to the next thought. It is not clear if the ideal paragraph has five, six, seven, a maximum or a minimum number of sentences, as it is not clear what one thought is, where or how it begins, and where or how it ends. On second thought, one could as well argue that every sentence consists of one thought.
