284 Then, what is the average of the numbers of the above series? In each of the following questions a number series is given. One term of the series is denoted by X. You have to calculate the value of  X and by using the value of  X, you have to replace the question mark (?) in the following questions :Solution
204 (-2³),  196 (+3³),  223 (-4³),  159  (+5³),  284 Hence, x= 159 Hence, average = (204+196+223+159+284)/5 = 1066/5 = 213.2
