Answer: 1000
Step-by-step explanation:
The sum of an arithmetic progression is Sn = n/2 (2a + (n-1)xd)
where n is the number of terms and a is the first term. d is the difference between the terms.
So : Sn = 10/2 (2(111) + (10-1)x1) = 1155
So 1155 - 1155 = 1000
Answer to your question is 155 + 1000
