The nth term is 3(n+1). The twenty-third term is equal to 3 x (23 + 1) = 72
It is an arithmetic sequence if you can establish that the difference between any term in the sequence and the one before it has a constant value.
The nth term of an arithmetic sequence = a + [(n - 1) X d]
An arithmetic sequence

One number, such as 7101316 does not define a sequence.
The one number, 491419 does not constitute a sequence!
What your tutor wants is for you to identify the factors of 21 and of 56. From this information you will find it easy to answer the question. good luck
No, the sequence 3, 6, 12, 24 is not an arithmetic sequence. In an arithmetic sequence, the difference between consecutive terms is constant. Here, the differences are 3 (6-3), 6 (12-6), and 12 (24-12), which are not the same. This sequence is actually a geometric sequence, as each term is multiplied by 2 to get the next term.
It is a + 8d where a is the first term and d is the common difference.
