Check if the interval of x is 1 and the interval (difference) between consecutive given numbers of y are the same.If they are the same, the mapping is linear, hence consecutives are obtained by adding the interval (difference)to preceding numbers.Interval/difference = 5 - 3 = 11 - 9 = 2Since the intervals are the same, the succeeding numbers are obtained by adding the difference to theirpreceding.p = 5 + 2 = 7q = 11 + 2 = 13
