Step-by-step explanation:
In the second column, we can see that every value of n is being added by 6.
- Thus, the expression is n + 6.
Now, let's substitute the value of n in each column to verify each column. Then, using the expression, let's find the value of n + 6 where n = 28.
When n is 12:
- n + 6 = 18
- 12 + 6 = 18
- 18 = 18
When n is 15:
- n + 6 = 21
- 15 + 6 = 21
- 21 = 21
When n is 21:
- n + 6 = 27
- 21 + 6 = 27
- 27 = 27
Thus, the expression is proven correct. Now, let's find n + 6 when n is 28.
Finding n + 6 when n is 28:
- n + 6 = x
- 28 + 6 = x
- 34 = x
Thus, the missing value in the table is 34.
