Question

the n th term of an AP is (2n-3) find the n th term

Answer 1

Nice question......
You have $\ T_{n}$ = (2n-3)
=> $\ T_{n}$ = { -1 + (n-1)2 }
Soo,
The A.P. can be -1, 1, 3, 5, 7, 9 ,......  Therefore $\ T_{n}$ is an odd positive integer...... Well, I can't help further if I don't have further details.....
