Hey there!!
Here's your answer..
Let us consider the A.P to be a, a+d, a + 2d .............
By this pattern, the 10th term would be a10 = a + 9d
The 15th term would be a15 = a + 14d
Given that
10 (a10) = 15 (a15)
Dividing with common factor 5, we get
2 (a10) = 3 (a15)
2 (a + 9d) = 3 (a + 14d)
2a + 18d = 3a + 42d
So, a + 24d = 0
Since a + 24d = 0, a25 is zero. Hence, the 25th term is zero.
Prateek declares that the 25th term is non zero which is incorrect. I don't agree with that.
Hope it helps !!
