Median is the middle number in a sorted list of numbers.
Hence if the median is 2 and to the maximum of x in value, below is how you should see
0 | 1 | 2 | 2 | 3 |
2x+1 | 7 | 4 | 1 | 3x+2 |
∴ 2x +1 + 7 + 4 = 3x + 2
3x – 2x = 1+7+4-2
x = 10
Thank bbcxd, but how do we know we must separate 4 and 1 out from 5?
Because the medium is 2 and to the maximum of x, it can only be the last 2 just before 3. Hence, we separate the 5 of 2 into 4 and 1. Hope this make sense.
