Ah....you shoulda' stayed on that cruise, Sincerelyrose....sounds WAY more exciting than this math stuff!!!

 

1+5=18

2+10=36

3+15=54

4+20= ?

 

 

Notice.....here's one possibility.....

 

1(13) + 5  =  18

2(13) + 10 =  36

3(13) + 15  = 54

4(13) + 20 = 72

Note that other schemes ARE possible...for example

 

3(1 + 5)  =  18

3( 2 + 10)  = 36

3(3 + 15) =  54

3( 4 + 20) = 72

 

Others on here may also see more "tricks"
