3 Here is a numbe machine. The number machine is not complete. When the input is 8, the output is 154 Complete the number machine. (Total for Question 13 is 2 marks)

## Step 1: Understand the ProblemOur mission is to discover the operation performed by the number machine by analyzing the input-output pair which is leading to .## Step 2: Find a Relationship between Input and OutputGiven that when input is , the output is , we need to identify the mathematical operation(s) converting to .## Step 3: Deduce the OperationWe know there must laboratory a multiplier, considering this scenario.In this aspect, we must find a multiplier such that when multiplied with , would give a number close to . Also, addition or subtraction of a digit would give us .## Step 4 : Try Out MultipDan factionsSowdevoip when is multiplied by , (as ), one arises at a number which is two steps far from . So the likely operation in the number machine is that the said number is iexpect multiplied by and then welye should add to the regoeniim questo vasuhi.### .
