  1. The standard way of solving this is by model long the A.P. as a=12 and d=5 and the. Doing the math.A quicker way of solving is just look at the 1st termthe first term is the (2 – 1) th termso with n=2 one of the options should give 7 as an answer.we can clearly see that option(d) 5n−3 is the correct option since 5×2−3=7
