The missing terms of the sequence are 84, 164 and 244
How to determine the missing terms of the sequence
From the question, we have the following parameters that can be used in our computation:
a(1) = 4
a(5) = 324
The nth term of an arithmetic sequence is represented as
a(n) = a(1) + (n - 1) * d
Using the above as a guide, we have the following:
a(5) = a(1) + 4d
So, we have
4 + 4d = 324
4d = 320
d = 80
Using the above as a guide, we have the following:
a(2) = 4 + 80 = 84
a(3) = 80 +84 = 164
a(4) = 80 + 164 = 244
Hence, the missing terms of the sequence are 84, 164 and 244
