Want this question answered?
A(1) = 12A(4) = 3 A(10) = -15.
You take the difference between the second and first numbers.Then take the difference between the third and second numbers. If that difference is not the same then it is not an arithmetic sequence, otherwise it could be.Take the difference between the fourth and third second numbers. If that difference is not the same then it is not an arithmetic sequence, otherwise it could be.Keep checking until you think the differences are all the same.That being the case it is an arithmetic sequence.If you have a position to value rule that is linear then it is an arithmetic sequence.
The answer depends on which steps you consider to be the first three. The sequence can vary.

The arithmetic average of seven consecutive odd number must be the fourth number which, by definition, is odd. If the average is not the arithmetic average, then the question is ambiguous. In either case the question has no valid answer.

To form a linear (or arithmetic) sequence you need two things: a starting value and the common difference. You have provided the common difference but not the starting value. If the starting value was a, then the nth term in the sequence would beT(n) = a + 5/4*(n - 1).
An arithmetic sequence is a sequence of numbers where the difference is constant. The difference between 1 and 1/4 is 3/4. The difference between 1/4 and 1/7 is 3/28. The difference between 1/7 and 1/10 is 3/70. These differences are not constant.
The one after "third" but before "fifth" in a sequence.
The cast of Blade af Satans bog - 1920 includes: Karina Bell as Naimi (fourth sequence) Hugo Bruun as Count Manuel (third sequence) Nalle Halden as The Majordomo (second sequence) Erling Hanson as John (first sequence) Hallander Helleman as Don Gomez de Castro (second sequence) Carl Hillebrandt as Rautamiemi (fourth sequence) Halvard Hoff as Jesus (first sequence) Wilhelm Jensen as Carpenter Tenna Kraft as Marie Antoinette (third sequence) Vilhelm Petersen as Fouquier-Tinville (third sequence) Elith Pio as Joseph (third sequence) Clara Pontoppidan as Siri (fourth sequence) Sven Scholander as Michonnet (third sequence) Jacob Texiere as Judas (first sequence) Jeanne Tramcourt as Lady Genevive de Chambord (third sequence) Viggo Wiehe as Count de Chambord (third sequence) Emma Wiehe as The Countess of Chambord (third sequence) Carlo Wieth as Paavo (fourth sequence)
