Answer:
C
Explanation:
There is a difference of 16 between consecutive terms, that is
259 - 243 = 275 - 259 = 291 - 275 = 16
This indicates the sequence is arithmetic with nth term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 243 and d = 16 , then
= 243 + 16(n - 1) = 243 + 16n - 16 = 227 + 16n → C
