Suppose 2,1 = 9 4,2 = 18 5,3 = 18 6,3 = 27 then 9,4= ?

Math Patterns are sequences that repeat based on a rule, and a rule is a set way to calculate or solve a problem.

Answer: 2,1 = 9 4,2 = 18 5,3 = 18 6,3 = 27. Then, then 9,4 = 45 and the solution is 94 - 49 = 45.

Let's try to understand the pattern.

Explanation:

The logic applied here is A,B = AB - BA

That means,

• 2,1 = 21 - 12 = 9
• 4,2 = 42 - 24 = 18
• 5,3 = 53 - 35 = 18
• 6,3 = 63 - 36 = 27

Similarly, 9,4 = 94 - 49 = 45.

Thus 9,4 = 45

Therefore, if 2,1 = 9 4,2 = 18 5,3 = 18 6,3 = 27 then 9,4 = 45.
