Math puzzle 1+4 = 5 , 2+5 = 12 , 3 + 6 = 21 , 8+11 = ?
Math puzzle
1+4 = 5
2+5 = 12
3 + 6 = 21
8+11 = 96
Confused? It may be the first line that is throwing you off, as if we use the a + ab equation, 1 x 4 equals 4. However, in the following lines the equation becomes clearer. For instance, 2 + 2(5) equals 12. So when used in the last line, 8 + 8(11), the final answer is 96.
