### Answer: 99

Explanation:

(3*2) + 1 = 7

(5*4) + 3 = 23

(7*6) + 5 = 47

(9*8) + 7 = 79

(10*9) + 9 = 99

There is one more pattern for this puzzle and with that pattern answer would be 98.

(3*2) + 2 – 1 = 7

(5*4) + 4 – 1 = 23

(7*6) + 6 – 1 = 47

(9*8) + 8 – 1 = 79

(10*9) + 9 – 1 = 98

Hi Kumar

I think the answer is 98; not 99.
Ie 10×9 + (9-1)

This formula fits all lines. There is a disruption to the pattern between the last two lines.

Your method would be correct if the last line was continuing the pattern (ie: was 11 x 10 instead of 10 x 9)

Have a great day
Nancy
