D) f(n) = 3 + 4(n-1)
3 = 1st term
4 = common difference among the terms
n = term number you are looking for.
To check: 3, 7, 11, 15, ...
f(1) = 3 + 4(1-1) = 3 + 4(0) = 3 + 0 = 3
f(2) = 3 + 4(2-1) = 3 + 4(1) = 3 + 4 = 7
f(3) = 3 + 4(3-1) = 3 + 4(2) = 3 + 8 = 11
f(4) = 3 + 4(4-1) = 3 + 4(3) = 3 + 12 = 15

Step-by-step explanation:
It is given that :
Initial temperature,
Final temperature,
Time taken :
Change in temperature per hour:
Putting the values of temperatures and time:
The error done by Wen was during calculating the values of fraction.
So, the correct answer is : instead of
A: -20b∧9
B: -3rx²y²+12x³y
C: -21m∧6+7m∧5+35m∧4
3 x 4 - + 2
With parentheses would be- (3 x -4) + 2
