Question

1,2=5 3,4=51 5,6=185 8,9=? Solve this problem

Answer 1

Answer:

8,9 = (8×9×9) + 8 = 656

Step-by-step explanation:

1st step : 1, 2 = ( 1×2×2) + 1 = 5

2nd step:  3,4 = (3×4×4) + 3 = 51

3rd step:   5,6 = ( 5×6×6) +5 = 185

First, you have to multiply two numbers like 1 and 2. Then, multiply the result with second number. After that, add the result with first number. This result is the final result.

Answer 2

Answer:

8,9 = 656.

Step-by-step explanation:

Given series:

1,2=5  

3,4=51  

5,6=185

Let's first analyze the common sequence or pattern in them.

It follows the below pattern:

a + a * b^2

For instance, in the first case: 1,2 = 5,

a=1; b=2;

1 + 1 * 2^2 = 1 + 4 = 5.

In the second case: 3,4 = 51,

a=3; b=4;

3 + 3 * 4^2 = 3 + 3 *16  = 3 + 48 = 51.

In the third case: 5,6 = 185,

a=5; b=6;

5 + 5 * 6^2 = 5 + 5 * 36  = 5 + 180 = 185.

Similarly,

For a=8; b=9;

8 + 8 * 9^2 = 8 + 8 * 81 = 8 + 648 = 656.
