ONLY 1 IN A THOUSAND OR A “GENUS CAN SOLVE THIS PROBLEM

1+4=5
2+5=12
3+6=21
8+11=?
Ok! Let’s start out: First of all, math is an exact science, there can be only 1 correct answer.
1. The answer must hold true for all the information given.
2. On the other hand, all the information must hold true.1+4=5, true. 2+5=12, not true.3+ 12=21, not true. Therefore the equation is either a lot of goobel-dy goop that cannot be correctly solved OR, there is information missing.
3. Let us explore some possibilities:1+4=5, 2x5+2=12, 3x6+3=21, 8x11+8=96; each line of the equation-information reads correctly.
4. Some people might claim there is ONE EXCEPTION=running total. They might try to claim the correct answer should be 1+4=5, 5+2+5=12, 12+3+6=221+8 +11 =40; once again each line APPEARS to read correctly.
5. However, a running total of 1+5=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 ALSO READS CORRECTLY and; makes more sense.By writing this solution out in a Column, as originally shown; it is easy to see how (add a few more numbers to the sequence, if you so desire;96+9+12=117, 117+10+13=140). this solution meets ALL requirements. THE correct answer is 96. There can only be the one.
