Answer:
Step-by-step explanation:
We begin with the equation
Next, we need to differentiate with respect to x
Now we need to solve for
To do this, we need to factor out the and then isolate it.
Yeahhhhhhhhhhhhhhhhhhhhhhhhhh and they did what???
This is an arithmetic series,
so
S(n) = (n/2)*(a(1)+a(n))
S(25) = (25/2)*(a(1)+a(25))
n=25
a(n) = 3n-2
a(1)= 3*1-2=1
a(1)=1
a(25) = 3*25-2=75-2=73
a(25)=73
S(25) = (25/2)*(1+73)=(25/2)*74=925
S(25)=925
Answer : 925
9053⁄<span>1997 would be it </span>hahah
