gemma writes 5 numbers. the median of these numbers is 17. she then writes a 6th number. the median of the six numbers in 18. write down the first 5 numbers and what the 6th could be.
15, 16 , 17, 18, 19
good lord im stupid
but in case when u have even amount of numbers then u have two meadians 15, 16 , 17, 18, 19, 20 in this case 17 & 18 are medians
add 1 and half it
no the median is the average of the two middle numbers so it can be 15,16,17,19,20 the 6th number could be anything greater then or equal to 19
no dear median of even 5, 15, 17, 34, 56 will be 17 !
its 17 if theres 5 numbers and if theres 6 numbers then the average of the two middle ones become the middle one in the case 15, 16,17,19,20,21 the 2 middle ones are 17 and 19 so to tak the average you go (17+19)\2 which equals 18
