Answer:
212 is the answer !
Explanation:
Firstly, We'll have to write all the numbers till 220 after 200 that is :
201 , 202 , 203 , 204 , 205 , 206 , 207 , 208 , 209 , 210 , 211 ,212 , 213 , 214 , 215 , 216 , 217 , 218 , 219 , 220 .
Here we now know the the 6th even number is 212.
And the 5th odd number is 209.
And the 8th odd number is 215.
By using the formula we can find the average that is :
212+209+215/3 = 636/3 = 212
∴ Your answer is 212 !
