If the 10 times of the 10th term of an AP is equal to 15 times to the 15th term, then the 25th term is:
2
1
25 times of 25th term
zero
Let a and d be the first term and common difference of an AP.
If 10 times the 10th term of an A.P. is equal to 15 times the 15th term, show that 25th term of the A.P. is zero.
If 8 times the 8th term of an AP is equal to 15 times the 15th term of that AP, then 23rd term of the same AP is
