If 3+3*4 = 28, 4+4*6=54, 5+5*7=77 then 6+6*9 = ??
6+6*9=117
(6*9)+(6*9)+9=117
answer is 117 3+3=6 6*4=24 24 will be added with the last digit of the series so 24+4
6+6=12, 2*9=108, 108 will be added with the last digit of the series so 108+9
Ans = 117 Solution: 1. 3+3*4=24+4 = 28 2. 4+4*6=48+6 = 54 3. 5+5*7=70+7 = 77 4. 6+6*9=108+9 = 117
The answer is 117
3+3+1=7×4=28 4+4+1=9×6=54 Similarlly 6+6+1=13×9=117
(6*9)+(6*9)+9 =54+54+9 =108+9 =117
