If considered number (n) obtained (49 in your case) is odd then middle number will be of (n+1)/2 term (25th term in your case)
If considered number (n) obtained is even then numbers at n/2 and (n+2)/2 terms will be the middle numbers.

One way is (100 +150) /2 = 125 .....that is the number that is exactly between 100 and 150.

You could simply lower 100 to 1 and 150 to 50, and divide 50 by 2, then add 100.

number me integers between then is =51
no divisible by 3:
102,105,108,111,114,117,120,123,126,129,132,135,13 8,141,144,147,150.
no divisible by 5:
100,105,110,115,120,125,130,135,140,145,150.
now strike out 105 120 135 150,as it is present in both.
so that
17+11_4=24
and 51-24=27

Thank you Captainblack; messed up on that one.

EDIT: I guess I should make up for it now; you could do 1 dollar/4. You could also, do 5/2, than move the decimal over two spaces.

As you can see, there are many problem solving applications which can be applied in these type of problems, most of which involve reducing the total sum in order to make the problem less complicated and than adding it on after you recieve your answer.
