Pls answer from exercise 14.1 a ​

b = 2a - 1

Step-by-step explanation:

a = 1 , b = 2 x 1 - 1 = 2 - 1 = 1

a = 2 , b = 2 x 2 - 1 = 4 - 1 = 3

a = 3, b = 2 x 3 - 1 = 6 - 1 = 5

a = 4, b = 2 x 4 - 1 = 8 - 1 = 7

b = 2a - 1

Step-by-step explanation:

We can see the pattern:

1 = 1 + 0 = 1 + 1 - 1

1 = 1 - 1

3 = 2 + 1 = 2 + 2 - 1

3 = 2 + 2 - 1

5 = 3 + 2 = 3 + 3 - 1

5 = 3 + 3 - 1

7 = 4 + 3 = 4 + 4 - 1

7 = 4 + 4 - 1
