i have been given a puzzle cube (4x4x4) which is meant to be composed from various differently shaped pieces of mainly five units each, similar to tetris shapes. I was wondering if there is a better way than trial and error of making the larger cube. Also, i was wondering if there was more than one way of doing it, other than the various rotations of the same solution.

These diagrams represent the first three trapezium numbers (each diagram always starts with 2 dots in the top row)

1st
OO

2nd
OO
OOO
OOOO
3rd
OO
OOO
OOOO
OOOOO

The 3rd trapezium number is 9 because 9 dots can be arranged as a trapezium.
There are 2 dots in the top row, 3 dots in the next row and 4 dots in the bottom row.

a)Write down two other trapezium numbers.
b)i) Find an expression for the number of dots in the bottom row of the nth trapezium number.

ii) Test your expression for a suitable value of n.
iii) Find, with an explanation, an expression for the number of dots in the bottom of the diagram for the (n+1) th trapezium number.

The nth trapezium number is x.

c)i) Write down an expression in terms of n and x for the (n+1)th trapezium number.

ii) Test your expression for a suitable value of n.

d)Obtain, with an explanation or justification a general expression in terms of n for the nth trapezium number.
