1. Pictorial explanation for adding Counting Numbers up and down to get square numbers: The idea is to visualise each term in the sequence as rows of dots, where the sum 1 + 2 + 3 + 2 + 1 can be arranged as a perfect square. For example, 1 + 2 + 1 forms a 2 x 2 square, 1 + 2 + 3 + 2 + 1 forms a 3 x 3 sRead more

    Pictorial explanation for adding Counting Numbers up and down to get square numbers:
    The idea is to visualise each term in the sequence as rows of dots, where the sum
    1 + 2 + 3 + 2 + 1 can be arranged as a perfect square. For example,
    1 + 2 + 1 forms a 2 x 2 square,
    1 + 2 + 3 + 2 + 1 forms a 3 x 3 square, and so on. Each layer of dots forms the next square by adding a symmetrical layer of dots around the existing square.

  2. Sequence When Adding the Counting Numbers Up: Adding the counting numbers up gives triangular numbers (1, 3, 6, 10, 15, …). Pictorially, we can visualise each sum as a triangle of dots, where each layer has one more dot than the previous layer. To see the complete Chapter 1, Visit here: https://www.Read more

  3. Sum of 1 + 2 + 3 + ... + 99 + 100 + 99 + ... + 3 + 2 + 1: This sequence will form a large square with side length 100, resulting in a sum of 100 × 100 = 10,000. This pattern holds because the symmetrical arrangement builds a square with the largest number (100) as its side length. To see the completRead more

  4. Sequence When Adding Pairs of Consecutive Triangular Numbers: When I add pairs of consecutive triangular numbers (e.g., 1 + 3 = 4, 3 + 6 = 9, 6 + 10 = 16, …), I get square numbers (4, 9, 16, …). This happens because each pair of triangular numbers combines to form a perfect square and I can represenRead more

    When I add pairs of consecutive triangular numbers (e.g., 1 + 3 = 4, 3 + 6 = 9, 6 + 10 = 16, …), I get square numbers (4, 9, 16, …). This happens because each pair of triangular numbers combines to form a perfect square and I can represent this pictorially by rearranging the dots of two triangular numbers into a square.

  5. Adding up powers of 2 starting with 1 and then adding 1: When we add up powers of 2 (e.g., 1, 1 + 2 = 3, 1 + 2 + 4 = 7, 1 + 2 + 4 + 8 = 15…) and then add 1 to each sum, we get the sequence 2, 4, 8, 16…, which are powers of 2 again. This happens because adding the sequence of powers of 2 up to a certRead more

    Adding up powers of 2 starting with 1 and then adding 1:
    When we add up powers of 2 (e.g., 1, 1 + 2 = 3, 1 + 2 + 4 = 7, 1 + 2 + 4 + 8 = 15…) and then add 1 to each sum, we get the sequence 2, 4, 8, 16…, which are powers of 2 again. This happens because adding the sequence of powers of 2 up to a certain point and then adding 1, results in the next power of 2. This pattern can be visualised by pictorially doubling the size of a block of dots each time.
