Vanessa is making a sequence of shapes out of tiles. She creates a table comparing the sequence number of a shape to the number of tiles needed to make it:

\text{Sequence} \\ \text{number } \left(n\right)123456
\text{Number of} \\ \text{tiles } \left(T\right)357
a

How many new tiles are added at each step?

b

Find how many tiles Vanessa will need to make the next three shapes in the sequence by completing the table of values.

c

An equation to represent the relationship between a shape's sequence number and the number of tiles needed can be written in the form T=s+(n-1)d, where s is the starting number of tiles and d is the number of new tiles added each step.

i
Write an equation to represent the relationship between a shape's sequence number and the number of tiles needed in the form given.
ii
Rewrite the equation found in the form T=an+b.
d

Find how many tiles Vanessa will need to make the 20th shape in the sequence.

James is making snowflakes out of hexagonal tiles:

He creates a table comparing the width of a snowflake to the number of tiles needed to make it:

\text{Width } \left(W\right)135791113
\text{Number of tiles } \left(T\right)171319
a

How many new tiles are added at each step?

b

Find how many tiles James will need to make the next three snowflakes in the sequence by completing the table of values.

c

Which of the following equations represents the relationship between a snowflake's width and the number of tiles needed?

A
T = 4W - 3
B
T = 1+ 6W
C
T = 6W-2
D
T = 3 W - 2
d

Hence, find the number of tiles required if the width of the snowflake is 21.
