The way of asking the question is wrong. It is known as common difference not common ratio. Here a = 1 , d= 3 a7=? we know that , an = a + (n-1)d a7= 1 +6x3= 19
2 and 1 .their sum is 3 .difference is 1

Since there are no graphs following, the answer is none of them.

The graph will be a set of disjoint points with coordinates [n, 0.5*(1+n)]

Find the 7th term of the geometric sequence whose common ratio is 1/2 and whose first turn is 5
An arithmetic-geometric mean is a mean of two numbers which is the common limit of a pair of sequences, whose terms are defined by taking the arithmetic and geometric means of the previous pair of terms.
