Hint
Look at the number of sides of each of the shapes.
Answer
Square.
Reasoning
If we add the shape's sides, the total increases by 8, then 10, then 12, etc (2 more each time).
triangle (3) + pentagon (5) + square (4) = 12
I recently travelled from my home town to a distant music concert, on a pedal tricycle, of all things! My wonderful, three-wheeled tricycle.
I knew that the epic 2,345 miles would wreak havoc on the tyres, but luckily I took along 4 spares!
Instead of waiting for any single tyre to fail, I decided that I would rotate the tyres evenly, making sure that by the end of the trip, all seven tyres had travelled exactly the same distance.
Reasoning
A total of 2,345 miles were travelled and at any one time, three tyres were on the tricycle.
Therefore, 3 x 2,345 = 7,035 tyre miles were travelled, which was shared equally by the 7 tyres.
And 7,035 ÷ 7 = 1,005.
