Answer:
2
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.
