Answer:
The 31st term is 84
Step-by-step explanation:
Here, we want to calculate the 31st term of the sequence
Firstly, we need to determine the type of sequence herein
As we can see;
200-204 = 196-200 = -4
The relationship between the numbers is a sum, that means the sequence is arithmetic
and; -4 represents the common difference
Mathematically, the nth term of an arithmetic sequence can be calculated using the equation;
Tn = a+ (n-1)d
with respect to the question;
a is the first term = 204
n = 31 and d = -4
Substituting these numbers;
T31= 204 + (31-1)-4
T31 = 204 - 4(30)
T31 = 204 - 120
T31 = 84
