Idon't know how to do this explain!

in an auditorium, there are 22 seats in the first row and 28 seats in the second row. the number of seats in a
row continues to increase by 6 with each additional row.
(a) write an iterative rule to model the sequence formed by the number of seats in each row. show your
work.
(b) use the rule to determine which row has 100 seats. show your work.

Demonstrate the proof of your new polynomial identity through an algebraic proof and a numerical proof in an engaging way! make it so the whole world wants to purchase your polynomial identity and can't imagine living without it! you must: label and display your new polynomial identity prove that it is true through an algebraic proof, identifying each step demonstrate that your polynomial identity works on numerical relationships create your own using the columns below. see what happens when different binomials or trinomials are combined. square one factor from column a and add it to one factor from column b to develop your own identity. column a column b (x − y) (x2 + 2xy + y2) (x + y) (x2 − 2xy + y2) (y + x) (ax + b) (y − x) (cy + d)
