It's technically called an arithmetic sequence
Since there are no graphs following, the answer is none of them.
An arithmetic sequence.
The graph will be a set of disjoint points with coordinates [n, 0.5*(1+n)]
It is a progression of terms whose reciprocals form an arithmetic progression.
Given an arithmetic sequence whose first term is a, last term is l and common difference is d is:The series of partial sums, Sn, is given bySn = 1/2*n*(a + l) = 1/2*n*[2a + (n-1)*d]

It is the sequence of first differences. If these are all the same (but not 0), then the original sequence is a linear arithmetic sequence. That is, a sequence whose nth term is of the form t(n) = an + b
We need help with answering this question.
Find the 7th term of the geometric sequence whose common ratio is 1/2 and whose first turn is 5
