First, draw a dot. Below that, draw two dots. Then, 3 dots below it and so on.
Here, you should see the pattern of the triangular number, which is the sum of consecutive integers starting at 1. The terms of that pattern are 1, 3, 6, 10, 15, ....n(1 + n)/2 where n is the total number of dots for the pattern.
What else can I help you with?
What is the 50th number in the triangular pattern?
The 50th triangular number can be calculated using the formula ( T_n = \frac{n(n + 1)}{2} ). For ( n = 50 ), this becomes ( T_{50} = \frac{50 \times 51}{2} = 1275 ). Therefore, the 50th number in the triangular pattern is 1275.
