    The odd one out is the 17 because it is not in the 4 time table.
    The 12 is the odd one out why because it is not a multiple of 4 group.

    -The whole intestine150cm +700cm = 850cm
    -The difference between the intestines 700cm-150cm= 550cm
    – Two skeletons will have 206+206= 412, we can also double of 206 or do 206×2= 412

    Gold
    5 tripods will have 5×3= 15 legs or 4 tripods will have 3×3= 9 legs
    9 Bipods will have 9×2= 18 legs or 7 Bipods will have 7×4= 14 legs
