Question

find the rule and complete the table.
in out
2
3 5
7 9
8 10
40
61 63

Explanation:

Step1: Identify the rule

By observing the pairs (3, 5), (7, 9), (8, 10), (61, 63), we can see that the rule is Out = In + 2.

Step2: Find the missing 'Out' value when In = 2

Using the rule Out = In + 2, when In = 2, Out = 2+2 = 4.

Step3: Find the missing 'In' value when Out = 40

Using the rule Out = In + 2, we can rewrite it as In = Out - 2. When Out = 40, In = 40 - 2=38.

Answer:

The first blank is 4, the second blank is 38.
