Tabulate and find the relationship between the variables (x and y) for the following patterns.
उत्तर
Let the number of steps be x and the number of shapes be y.
Tabulating the values of x and y
| Steps (x) | 1 | 2 | 3 | 4 | 5 |
| Shapes (y) | 1 | 3 | 5 | 7 | 9 |
From the table x = 1 ⇒ y = 1 = 1
x = 2 ⇒ y = 2 + 1 = 3
x = 3 ⇒ y = 3 + 2 = 5
x = 4 ⇒ y = 4 + 3 = 7
x = 5 ⇒ y = 5 + 4 = 9
Hence the relationship between x and y is y = 2x − 1.
