If 1+4=5, 2+5=12, and 3+6=21, what is 8+11? Viral math Puzzle answer
Answer: 8+11=96
Solution: Correct Answer: 8+11=96
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
Once again we get the answer of 96, that's surprising!

Alternate method :
a+b= a+b(sum of the previous equation)
1 + 4 = 5.
2 + 5 (plus the previous sum of 5) = 12.
3 + 9 (plus the previous sum of 12) = 21.
same logic will apply for last equation also
8 + 11 (plus the previous sum of 21) = 40.
