Answer:
The sum of the first 51 terms of the sequence is 6018
Step-by-step explanation:
AP: −282,−266,−250,−234,...
First term = a = -282
Common difference = d = 
Common difference = d = -266-(-282)=-250-(-266)=16
Formula of sum of first n terms =
Substitute n = 51
So,

Hence the sum of the first 51 terms of the sequence is 6018
Answer:
Step-by-step explanation:
15x + 12 + 10 - 20 = 12
15x + 22 - 20 = 12
15x + 2 = 12
15x = 12 - 2
15x = 10
x = 10/15 which reduces to 2/3
