FINDING RULE FOR THE PATTERN WITH TWO OPERATIONS

Write the rule in each double function machine. Each rule is made up of 2 operations (× then +).

Problem 1 :

Solution :

Multiply by the input 4 and add 2.

Rule :

Output = Input x 4 + 2 

Problem 2 :

Solution :

Multiply by the input 5 and add 1.

Rule :

Output = Input x 5 + 1 

Problem 3 :

Solution :

Multiply by the input 6 and add 2.

Rule :

Output = Input x 6 + 2 

Problem 4 :

Solution :

Multiply by the input 6 and add 2.

Rule :

Output = Input x 6 + 2 

The rule is given, find the output using inputs and the rule.

Problem 5 :

Solution :

Here rule is given. By applying inputs one by one into the rule, we will get output.

Problem 6 :

Solution :

Problem 7 :

The snow is 17 cm deep at 5 p.m. Each hour, 4 cm of snow falls. How deep is the snow at 9 p.m.?

Solution :

Height of snow at 5 p.m = 17 cm

Each hour height of the snow will increase by 4 cm.

At 9 p.m depth of snow is 44 cm.

Problem 8 :

Jin had $42 in savings by the end of July. Each month he saves $9. How much will he have by the end of October?

Solution :

Jim's savings at the month of July = $42

Each month he saves $9. His savings will increase $9 every month.
