1+4=5 , 2+5=12, 3+6=21 , 8+11=?
Solution: 1 If you look at first 3 Equations a + b means a + ab a+b => a+ab Let see now how it works for all equations , 1 + 4 means 1 + 1(4) = 5 2 + 5 means 2 + 2(5) = 12 3 + 6 means 3 + 3(6) = 21 now will apply same formula for the last equation 8+11=? 8 + 11 means 8 + 8(11) = 96 So final answer is 96 is proved. Solution : 2 1 + 4 = 5 5 + 2 + 5 = 12 12 + 3 + 6 = 21 21 + 4 + 7 = 32 32 + 5 + 8 = 45 45 + 6 + 9 = 60 60 + 7 + 10 = 77 77 + 8 + 11 = 96
