Let the first term = a and common difference = d of the First A.P.

and the first term = a1 and common difference = d1 of the Second A.P.

Here we have to find ratio of 9th term So n will be 2k -1 where k will be 9

Then n = 2k-1 = 2 x 9 - 1 = 17

Now putting the value n = 17 in above equation

Hence Ratio of 9th term = 59:134 Answer
