The third term of the sequence is 11 and this can be determined by using the given data and the arithmetic operations.
Given :
Recursive rule -- f(1) = 3, f(n) = f(n - 1) + 4
The following steps can be used in order to determine the third term of the sequence:
Step 1 - According to given data, f(1) = 3.
Step 2 - Now, substitute the value of n = 2 in the expression (f(n) = f(n - 1) + 4).
f(2) = f(2 - 1) + 4
f(2) = f(1) + 4
f(2) = 3 + 4
f(2) = 7
Step 3 - Now, substitute the value of n = 3 in the expression (f(n) = f(n - 1) + 4).
f(3) = f(3 - 1) + 4
f(3) = f(2) + 4
f(3) = 7 + 4
f(3) = 11
