Right then. Finding the sum of a series entirely depends on the type of series you have. Your first job is to identify it.

Check if there’s a common difference between the terms. If so, it’s an arithmetic series. The sum is just the number of terms times the average of the first and last term. Simple as that.

If there's a common ratio instead, you've got a geometric series. There's a specific formula for this which is easy enough to find. If your series is neither, things get a bit more advanced, but these two will cover most cases you'll see. Cheers.

The sprint review is basically a show-and-tell for the work we just finished in a sprint. The team shows the product owner and stakeholders what they built. It’s more than just a demo, though. The real purpose is to get feedback on the actual product increment.

Stakeholders can see the progress. They can ask questions and give their ideas. This conversation helps the Product Owner adjust the Product Backlog for the next sprints. It makes sure everyone is on the same page and that we are building the right thing.

So, it’s all about inspecting the work and adapting our plans based on real feedback. It’s a super important collaboration meeting, not a status report.

Actually, there is no official new name for India. But there is a lot of discussion about this in the news right now. You see, our constitution already says "India, that is Bharat." So both names have always been official. 'Bharat' is a very old and traditional name for our country.

Recently, our government has started using 'Bharat' more in official things. For example, the G20 summit invitation said 'President of Bharat'. This is why everyone is talking about a name change. But as of now, no law has been passed to change anything. So you can still use both India and Bharat. Both are correct and mean the same country.

Most debit cards from the bank do not work for lounge access. You need to have a special kind of debit card. These usually come with a premium or high-level bank account.

The best way is to call your bank. Use the phone number on the back of your card. Ask them if your card has a "lounge access program". Sometimes the program is called Priority Pass or LoungeKey.

If you have it, you might need to sign up online first. You must do this before you go to the airport. At the lounge, you just show your card. They may charge a small amount to make sure the card is active. Also, check how many free visits you get per year.

Right then. In simple terms, jqe360 is a JavaScript tool. It's a plugin that works with jQuery. Its main job is to create those interactive 360-degree product viewers. You've definitely seen them on shopping websites. They let you click and drag to spin a product around for a proper look. A developer just needs a whole stack of photos of an object from every angle. The plugin then stitches them all together to create that smooth rotating effect. It’s a pretty neat way to show off a product online, I reckon.

Amdahl's Law is a formula used in computer architecture. It calculates the maximum potential speedup you can achieve when improving a part of a system. The key idea is that the overall speedup is limited by the fraction of the task that cannot be parallelized. For example, if 10% of a program is serial, you cannot speed it up beyond 10x, no matter how many processors you use. It highlights the importance of optimizing the sequential parts of any code for better performance gains.
