Given series is,

ODD EVEN = RELATION

3 2 7 ( 3*2+1)

5 4 23 (5*4+3)

7 6 47 (7*6+5)

9 8 79 (9*8+7)

Following the series we concluded that, Next term in this series must be,

11 10 119 (11*10+9)

But for confusing, the question term is of different nature of,

10 9 ??

Hence the problem is from a complete series of the following type,

3 2 7 ( 3*2+1)

4 3 14 (4*3+2)

5 4 23 (5*4+3)

6 5 34 (6*5+4)

7 6 47 (7*6+5)

8 7 62 (8*7+6)

9 8 79 (9*8+7)

10 9 98 (10*9+8)

11 10 119 (11*10+9)

Hence the answer must be 98
