Answer:
origin.......................
180= x+24+6x+18+2x+30
180= 9x+72
108=9x
X=12
And its 6 600 and 202 and add 100 which means it will be 12 THATS your answer
An = 2n + 2
a1 = 2(1) + 2 = 2 + 2 = 4
a2 = 2(2) + 2 = 4 + 2 = 6
a3 = 2(3) + 2 = 6 + 2 = 8
a4 = 2(4) + 2 = 8 + 2 = 10
a5 = 2(5) + 2 = 10 + 2 = 12
84 is the median of the numbers
