Expert Answer:

to findthe nth term in an aap we can use the formulae

nth term=first term+(n-1)d    where d=common difference

a ,x1 ,x2,b are in ap 

so there are 4 terms and b=a+3(x2-x1)

x2-x1=(b-a)/3

simillarly a,y1,y2,y3,b are in ap and here total 5terms ,so b=a+4(y2-y1)

y2-y1=(b-a)/4

now , (y2-y1)/(x2-x1) =(b-a)/4/(b-a)/3 = 3/4                            answer
