Answer:
n = 53
Explanation:
The n th term rule for an arithmetic progression is
= a + (n - 1)d
where a is the first term and d the common difference
d = 11 - 4 = 7 , a = 4 and
= 368, hence
4 + 7(n - 1) = 368
4 + 7n -7 = 368
7n - 3 = 368 ( add 3 to both sides )
7n = 371 ( divide both sides by 7 )
n = 53
