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
those would be linear sequences......sequences which are always increasing by the same number such as..... 2, 4, 6 ,8.....those are always increasing by 2. This is so because their rule is 2n which is in the form of the equation which is straight when plotted such as y=2x Sean

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