explained below:
I) 3+2=7 (3*3-2) 1st no. 3, 2nd no. 2
II)5+4=23 (5*5-2) 1st no. 5, 2nd no. 4
III)7+6=47 (7*7-2) 1st no. 7, 2nd no. 6
IV)9+8=79 (9*9-2) 1st no.9, 2nd no. 8
The sequence of these additions are odd no and even no. 3,5,7,9,11..... + 2,4,6,8,10.... respectively which equals to the square of odd no in each sum nd subtractin 2 from it.
Continuing sums can be 11+10=119, 13+12=167....
