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:
Answer:
17
Step-by-step explanation:
24x+24=27x-27
51=3x
x=17
It means 3 multiplied by 4
