Question

1+4=5, 2+5=12, 3+6=21 , 8+11=?

Answer 1

If there is a pattern here to follow then the person before is wrong. If there is no pattern then you are wrong with all of the answers there

8+11=40 This is because in this pattern you take the equations before answer and add it to the equation you have so for the first equation you have 5 for the second equation you actually add 2+5+5=12 so the last one equals 8+11+21=40

Hope This helps!
