If the mean of numbers 28, x, 42, 78 and 104 is 62, what is the mean of 48, 62, 98, 124 and x?

Answer 1

78

Let's calculate the first mean: #(28+x+42+78+104)/5=(x+252)/5=62# From the last equality we can conclude that #x+252=62*5# and finally #x=62*5-252=58# Now, we can simply evaluate the second mean: #(48+62+98+124+x)/5=# #=(48+62+98+124+58)/5=390/5=78#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
