Question

The chart below shows the relationship between two values, A and B.

A B
2 30
4 40
8 50
____ 60
32 70
64 80

Given the relationship, what would be the value of A that is missing?

Answer 1

The pattern in the data shows that as A doubles, B increases by 10. To find the missing value of A for B=60, we determine that A should be 16 when B is 60 as it fits the observed doubling pattern.

Step-by-step explanation:

Looking at the given data chart, there is a clear increase in value B as value A increases. To determine the missing value of A where B is 60, we need to recognize the pattern between A and B. The pattern suggests that as A doubles, B increases by 10. Let's observe the pattern:

• A = 2, B = 30
• A = 4, B = 40
• A = 8, B = 50
• A = ?, B = 60
• A = 32, B = 70
• A = 64, B = 80

If we continue this pattern, doubling A from 8 to 16 should correspond to B increasing by 10 from 50 to 60. Therefore, the missing value of A is 16 when B is 60.
