Recognise that a sequence is linear sequences when expressed as a pattern Tom and Katie are discussing linear sequences Tom says this is a linear sequence: ![Three shapes made of squares. The first is an L-shape made of 3 squares so the bottom line is two squares long. The second shape is also an L but with a bottom line of three squares. The fourth shape is the same but the bottom line is four squares long.  ]() Katie says this is a linear sequence: ![Three shapes made of squares. The first is an L-shape made of 3 squares. The second shape is an L made of 5 squares, two on the top row and three on the bottom row. The third shape is an L made of 7 squares, 3 on the top row and four on the bottom. ]() Who is correct?
