Explanation Given: T ( n ) is the total number of matchsticks in the n th figure. Approach: Use any pattern of matchsticks to find the answer. Calculation: The following figure shows the arrangement of matchsticks. The first figure contains only one square. The second figure contains two squares and so on. The number of matchsticks in each figure follows the pattern: 4 , 7 , 10 , .. and so on. Th number of matchsticks in each figure represents arithmetic progression with a common difference of 3 . Now, finding the number of matchsticks in the n th figure
