**Step-by-step explanation:**

This is an arithmetic series.

6 , 11 , 16, 21 ,.....

First term = = 6

Common difference = d = second term - first term

= 11 - 6 = 5

nth term =

= 6 + (n - 1) * 5

= 6 +5n - 5

= 6 - 5 + 5n

= 1 + 5n

**Answer:**

151

**Step-by-step explanation:**

m=150cm

n=30

new mean =(m*n+165-135)/n

=(150*30+165-135)/30

=(4500+30)/30

=4530/30

=453/3

=151

therefore

correct mean =151

Hope this helps :D
