Every day we will share one Math question. You can solve it and share your solution in the comments below. The next day, we will post the method of solving today’s question and answer any of your subsequent questions in the process. Click on the post, read the question and share your answer in the comments below. Today’s question is on Algebra – Linear equations using one variable.

While we learn the structured way of solving the problem, knowing how to solve the problems when they appear in entrance exams where we have a time constraint gives us the edge. If you had only 30 seconds to solve this, how would you approach it?

Now, let us see the quick computation

If you have understood the above, answer this –

Does this work if the number of consecutive numbers is EVEN? (For example: Instead of 7 consecutive numbers, what if there were 8 consecutive numbers). How would you compute the largest number then? Share your answers in the comments section below.
