\(8\) consecutive odd integers with increasing values
The terms \(= 2a - 7, 2a - 5, 2a - 3, 2a - 1, 2a + 1, 2a + 3, 2a + 5, 2a + 7\)
7th term \(= 9 = 2a + 5\)
\(a = 2\)
Sum \(= 16a = 32\)
Answer B
The terms \(= 2a - 7, 2a - 5, 2a - 3, 2a - 1, 2a + 1, 2a + 3, 2a + 5, 2a + 7\)
7th term \(= 9 = 2a + 5\)
\(a = 2\)
Sum \(= 16a = 32\)
