Answer:

5th number = 31

Step-by-step explanation:

mean = sum of observation/number of observations

mean =25

number of observation = 5

25= sum of observation / 5

sum of observation= 25*5

sum of 5 observation= 125

given 4 numbers =16,26,20,32

sum of 4 numbers = 16+26+20+32= 94

difference b/w

(sum of 5 observation - sum of 4 observation)

= 5th number

= 125-94

= 31

verification sum of 5 observation= 16+26+20+32+31

= 125

mean = 125/5

= 25
