Given,
nth term of A.P. :
∴ Tn = 2n + 5
⇒ T10 = 2(10) + 5
= 20 + 5
= 25.
Hence, option 3 is the correct option.

The first term of an A.P. is 7 and the common difference is 3. The general term of the A.P. is:
Tn = 3n − 4
Tn = 2n + 5
Tn = 3n + 4
None of these
The 24th term of the A.P. −1, 3, 7, 11, … is:
83
87
