Question

If the number in the center is the sum of the rest of the numbers, find value of b

​

Answer 1

Given data:

The number in the center is the sum of the rest of the numbers

To find:

The value of b

Step-by-step explanation:

Here the numbers are 5, b, 3b and 3

Thus their sum is (5 + b + 3b + 3) = 8 + 4b

Since the middle number is not given, we can assume its value and solve for b

Case 1.

• Let the center number be 8
• Then, 8 + 4b = 8
• ➾ 4b = 0
• ➾ b = 0

Case 2.

• Let the center number be 12
• Then, 8 + 4b = 12
• ➾ 4b = 4
• ➾ b = 1

Case 3.

• Let the center number be 16
• Then, 8 + 4b = 16
• ➾ 4b = 8
• ➾ b = 2

In this way, we can find more values of b.

Answer:

With our assumptions, we have found b = 0, 1, 2, ... .
