those lines mean "absolute value of"
if you thought of it like money "I have $20" the value is $20
but if you owed $20 you would have -$20 but the total value to the economy is still $20

Answer: 11
Step-by-step explanation:
From the question,
a = first term= 2
3rd term = a + 2d = 4
2 + 2d = 4
2d = 4-2
2d = 2
Commons difference = d = 2/2 = 1
10th term = a + (n-1)d = a + (10-1)d = a + 9d
= 2 + 9(1)
= 2 + 9
= 11
The 10th term is 11
Answer: The correct answer should be 7.6128
