Answer:
495
Step-by-step explanation:
In order to find the sum of the first 18 terms you have to find the 18th term and the first term using the equation given.
a1=3(1)-1 a1=2
a18=3(18)-1 a18= 53
Then plug in 53 for an, 18 for n, and 2 in for a1 in the sum equation: Sn=n/2(a1+an)
Sn=18/2(2+53) Solve for sn= 495
I believe the anwser is c.
a = ( 1 , 6 )
b = ( 4 , 9 )
Now just need to put the coordinates in the above equation :
And we're done...♥️♥️♥️♥️♥️
