Answer 1

n here is an odd number. n+2,n+4,..... are the consecutive odd numbers. that means they are the next odd numbers of n. I hope you understand my solution

Answer 2

Answer:

149

Step-by-step explanation:

Average =  Sum of observations / No. of Observations

   

147 =           x+x+2+x+4+x+6+x+8 / 5

147*5 =   5x+20

735 - 20 = 5x

715 = 5x

715/5 = x

143= x

Second largest no. in the list is x+6

x+6 = 143+ 6 =  149
