Q.1.2 How many dots would be in the 7th row? (3) 1st row: . 2nd row: . . . 3rd row: . . . . . 4th row: . . . . . . A. 7 B. 10 C. 11 D. 13 E. 15

In this pattern, each row adds an additional dot compared to the previous row, starting from 1 dot in the 1st row. So the 1st row has 1 dot, the 2nd has 3 dots, the 3rd has 5 dots, and the 4th row has 7 dots. Following this pattern, the 7th row will have 13 dots since it continues the sequence of adding 2 more dots for each additional row. Thus, the answer is D. 13. But why stop there? This is a lovely example of an arithmetic sequence, where we can see how patterns build on each other. Understanding these patterns not only helps in mathematical reasoning but can also be applied in areas such as computer science algorithms, where efficiency and systematic logic are crucial. Keep your eyes peeled for these patterns in everyday life; they pop up everywhere!
