2+6+5= 121015 | 12+10= 22-7=15
6+7+8= 424881 | 42+48= 90-9=81

    3+6+7=1821213+6+7=183104 as i amnot getting certain relation bet last two digits. This is guess work. In 1st and 3rd equation add all numbers-2= last two digits i.e.2+5+8+1+1+6=23-2=21 and 2+6+5+1+2+1=17-2=15 or another relation is middle two digits +5=last two digits. i.e. 16+5=21 and 10+5=15 similarly for 2nd anf 4th add 4+2+4+8=18 reverse digits are last two digits 3+6+7=182121 or other option is (4th digit +1)square = last two digits i.e. 8+1=(9)square =81 so 4th will be 3+6+7=182104
