Answer:
= 1
Step-by-step explanation:
The n th term of an arithmetic progression is
= a + (n - 1)d
where a is the first term and d the common difference
use the 9 th term and 7 th term to find a and d
= a + 8d = → (1)
= a + 6d = → (2)
Subtract (2) from (1) term by term
2d = ⇒ d =
Substitute this value into (2) and solve for a
a + =
a = - =
Hence
= + = 1
