Answer:
21, 17, 13
Step-by-step explanation:
Find the mean of the 2 given values
mean = [tex]\frac{25+9}{2}[/tex] = [tex]\frac{34}{2}[/tex] = 17
Noe find the mean of 25 and 17 and 17 and 9
mean = [tex]\frac{25+17}{2}[/tex] = [tex]\frac{42}{2}[/tex] = 21 and
mean = [tex]\frac{17+9}{2}[/tex] = [tex]\frac{26}{2}[/tex] = 13
Thus the 3 means are 21, 17 and 13, that is
25, 21, 17, 13, 9
