Answer 1

To determine the seventh term of the sequence given by the first five terms 19, 15, 11, 7, 3, we can observe the pattern in the sequence.

The sequence decreases by 4 between consecutive terms:

• \(19 - 15 = 4\)
• \(15 - 11 = 4\)
• \(11 - 7 = 4\)
• \(7 - 3 = 4\)

Continuing this pattern, we can find the subsequent terms:

• The 6th term \(a_6\) is \(3 - 4 = -1\)
• The 7th term \(a_7\) is \(-1 - 4 = -5\)

Therefore, \(a_7 = -5\).

The correct response is: a7=−5
