Use a linear sequence expressed as a pattern to make a prediction about another term in the sequence other than the next one Jo and Paul are arguing about the best way to count the number of squares in Pattern \( 15 \).
Jo does: \( 15 \times 3+4 \)
Paul does: \( (15+2) \times 3-4 \)
Who is correct? ![The 3rd and 4th terms in a sequence of patterns. Each pattern is made from red squares. Pattern 3 is 11 squares: they are arranged as a rectangle, 3 squares high and 3 squares wide and then 2 more squares, 1 each side of the middle squares (vertically). Pattern 4 is 14 squares arranged as a rectangle, 3 squares high and 4 squares wide and then 2 more squares, 1 each side of the middle squares.]() Only Jo

Believes nth term rules for patterns must be given in standard an + b form
