There can surely be a benefit in being the "weakest", in the sense that you are surrounded by more experienced team members from whose experience you can profit. However, whether or not this really works out depends on you, the team, and the "gap" in experience.
For it to work, you must show that you are trying, i.e., don't only rely on the others. Prove that you can do things on your own and that you learn from what they show you. If you keep asking the same questions your teammates will surely get annoyed soon.
For it to work, your teammates must be open minded (and maybe experienced enough) to take in a new team member. Sometimes people get arrogant (surprisingly this happens most often to those who are actually not too far ahead themselves) and therefore act as if the new one is stupid. In this case I recommend to get this right onto the table in the next team meeting. Don't be afraid to talk to your team about problems your experiencing. A team that cannot reflect on itself cannot function properly.
Something else you can do, if you don't want to go all out directly, is talking to the last member that joined the team before about his time as the "weakest". Or, if that's not the right person for you to talk, chose a senior team member you feel comfortable talking to.
A remark on the notion of "weakness". In my experience it is seldom helpful to anyone to regard yourself as weak. I'm sure you have your accomplishments and your strengths. Only you are new on the ground you're walking and you need some time to get used to it. Such an orientation phase is not a weakness, but a perfectly normal and healthy thing. After all, it made you reflect on your role in the team. Image what would happen if somebody new joins the team and starts to tell everybody how to do things, right-away! It's good to have respect (and sometimes a little self-doubt) when facing something new. This is what makes us strive to become better.
