A triangular number is formed by adding consecutive numbers like 1, 1+2, 1+2+3, and so on. You can find the nth triangular number using the formula n(n+1)/2.
How do I solve missing number puzzles in sequences?
Look at the difference between consecutive numbers or check if they are multiplied, squared, or follow a special pattern like triangular numbers.
Why are square numbers called square numbers?
They are called square numbers because the dots representing them can be arranged neatly into equal rows and columns to form a geometric square.
