Andrea is designing the seating arrangement for a concert in her local park. to give everyone a good view, each row must have 4 more seats than the row before it, and the 1st row can only have 10 seats. andrea plan the rest of the seating by solving for how many seats are in row 20. then explain to andrea how to create an equation to predict the number of seats in any row. show your work, and use complete sentences.

86

Step-by-step explanation:

a20 = a19 = a18 = a17 = a16 = a15 = a14 = a19 = a13 = a12 = a11 = a10= a9 = a8 = a7 = a6 = a5 = a4 = a3 = a2 = a1

row 1 = 10

row 2 = 14

row 3 = 18

row 4 = 22

row 5 = 26

row 6 = 30

row 7 = 34

row 8 = 38

row 9 = 42

row 10 = 46

row 11 = 50

row 12 = 54

row 13 = 58

row 14 = 62

row 15 = 66

row 16 = 70

row 17 = 74

row 18 = 78

row 19 = 82

row 20 = 86

So the guy above me is right with his math :)

it is b)

hope this : )
