For the following input numbers, calculate output numbers under the given rules :
Question 1 :
Four times the input number.
Solution :
Let us consider "n" as input value and "m" as output value.
Rule ==> Four times the input number.
Formula :
m = 4n
Input n = 1 n = 2 n = 3 n = 4 |
Output m = 4(1) ==> 4 m = 4(2) ==> 8 m = 4(3) ==> 12 m = 4(4) ==> 16 |
Question 2 :
The input number plus three.
Solution :
Rule ==> The input number plus three.
Formula :
m = n+3
Input n = 4 n = 6 n = 12 n = 26 |
Output m = 4+3 ==> 7 m = 6+3 ==> 9 m = 12+3 ==> 15 m = 26+3 ==> 29 |
Question 3 :
Add two then multiply by 3
Solution :
Rule ==> Add two then multiply by 3
Formula :
m = 3(n+2)
Input n = 0 n = 1 n = 2 n = 5 |
Output m = 3(0+2) ==> 6 m = 3(1+2) ==> 9 m = 3(2+2) ==> 12 m = 3(5+2) ==> 21 |
Question 4 :
Multiply the input number by itself.
Solution :
Rule ==> Multiply the input number by itself.
Formula :
m = n ⋅ n
Input n = 1 n = 2 n = 3 n = 5 |
Output m = 1 ⋅ 1 ==> 1 m = 2 ⋅ 2 ==> 4 m = 3 ⋅ 3 ==> 9 m = 5 ⋅ 5 ==> 25 |
Question 5 :
Double the input number then add one.
Solution :
Rule ==> Double the input number then add one.
Formula :
m = 2n+1
Input n = 1 n = 2 n = 3 n = 8 |
Output m = 2(1)+1 ==> 3 m = 2(2)+1 ==> 5 m = 2(3)+1 ==> 7 m = 2(8)+1 ==> 17 |
Question 6 :
Subtract 3 then multiply by 2.
Solution :
Rule ==> Subtract 3 then multiply by 2.
Formula :
m = 2(n-3)
Input n = 3 n = 4 n = 10 n = 15 |
Output m = 2(3-3) ==> 0 m = 2(4-3) ==> 2 m = 2(10-3) ==> 14 m = 2(15-3) ==> 24 |
