Question

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

KnowledgeBoat · Accepted Answer

We know that, nth term of A.P. : ∴ Tn = a + (n - 1)d Given, a = 7, d = 3 Tn = 7 + (n - 1)3 = 7 + 3n - 3 = 3n + 4. Hence, option 3 is the correct option.
