Answer:
1800
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
= 
[ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = - 27 and d = 6, thus
= 
[ (2 × - 27) + (29 × 6) ]
= 15( - 54 + 174)
= 15(120)
= 1800
6w=30; divide 30 by 6 to the w by itself; the answer is 5
1/8
I’m adding random stuff to send the answer!:)
If you took a better picture I would be able to solve it. Sorry it is pretty blury
