Chairs for an orchestra are positioned in a curved form with the conductor at the center. The front row has 16 chairs, and each successive row has 4 more chairs. Write an explicit rule to describe its pattern. How many chairs are in the 6th row?

Question

anonymous · Answer

your rule should be...
y= 16+4x-4
the 16 is the orginal chairs
the 4x is the amount of rows (x) times 4 (since four is added)
and the -4 is because you don't add 4 to the first row.
so...
row 1 =16
row 2 = 20
row 3=24
row 4= 28
row 5= 32
and row 6 = 36
Hope this helps

Would an = 16 + 4(n - 1) be the answer? @Master_General_B_C
