Multiply the number by 4. Add 2 to the product. Divide this sum by 2. Subtract 1 from the quotient. The first number is 1.

2

Step-by-step explanation:

According to the problem, calculation of the given data are as follows,

First number = 1

So by making the equation, we get

Multiply first number by 4

= 1 × 4 = 4

Add 2 to product

= 4 + 2 = 6

Now, Divide sum by 2

= 6 ÷ 2 = 3

Now, subtract 1 from the quotient

= 3 - 1 = 2

Hence, 2 is the correct answer.
