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
32 is the constant because it doesn’t have a letter
