Explanation Given: The two patterns are given as following: Approach: By counting the number of dots in each triangle by taking arithmetic progression for each row of triangle and then multiplying it by number of triangles and then calculating the number of other dots by taking the horizontal dots and adding it to the number of vertical dots with the help of arithmetic progression. Calculation: As in the first diagram the number of dots in each triangle is 1 + 2 + 3 + 4 = 10 and the number of triangles are 3 and for other dots using the arithmetic progression 1 + 2 + 3 + ..
