What are the possibilities of answeres 3*2=7 5*4=23 7*6=47 9*8=79 10*9=?

The answer is multiply the numbers and add odd number sequence.

For example: The product (y x z = x) is x. The odd numbers sequence is 1, 3, 5, 7, 9 etc. is added to the product. Add x + odd number sequence.

3 x 2 = 6 + 1 = 7

5 x 4 = 20 + 3 = 23

7 x 6 = 42 + 5 = 47

9 x 8 = 72 + 7 = 79

10 x 9 = 90 + 9 = 99

The answer is 99.
