The nth term from the end of an A.P., whose first term, last term and common difference are a, l and d respectively, is given by:

1. l + (n + 1)d

2. l − (n − 1)d

3. l + (n − 1)d

4. l − (n + 1)d

The nth term of an Arithmetic Progression (A.P.) is 2n + 5. The 10th term is :

1. 7

2. 15

3. 25

4. 45

The first term of an A.P. is 7 and the common difference is 3. The general term of the A.P. is:

1. T_n = 3n − 4

2. T_n = 2n + 5

3. T_n = 3n + 4

4. None of these
