Question

II. Answer the following:
9. Find the nth term of the A.P. 5, 7, 9, 11​

Answer 1

Answer:

AP Given- 5,7,9,11...

Find the nth term.

Explanation:

first term, a = 5

common difference, d = 7-5

                                      = 2

an = a + (n-1)d

an = 5 + (n-1)2

    = 5 + 2n -2

    = 3 + 2n

∴ nth term of AP-5,7,9,11..  is (3 + 2n).
