Evaluate the summation of 3 n plus 2, from n equals 1 to 14..

We have to evaluate the summation of (3n+2), with n ranging from 1 to 14. Let's write all the terms of the sum for each value of n:
n=1:
n=2: 
n=3: 
n=4: 
n=5: 
n=6: 
n=7: 
n=8: 
n=9: 
n=10: 
n=11: 
n=12: 
n=13: 
n=14:
Now, let's sum all the terms together, and we get:
