Answer:
f(x)=x^2+3
f(x+y)=(x+y)^2+3
this is done by replacing x with (x+y)
f(x+y)=x^2+2xy+y^2+3
therefore : f(x+y)= x^2+y^2+2xy+3

Subtract 2x from both sides (5y=1-2x) then divide by 5 (y=0.2-2/5x)
The missing number in the sequence is 52.
<h3>What is the missing number in the sequence?</h3>
In order to determine the missing number, the pattern in the sequence has to be determined.
The difference between the second and first number is 144 - 127 = 17
The third number is 3 times smaller than the second number: 144 / 48 = 3
The difference between the fourth number and the third number is 66 - 48 = 18.
The fifth number is 2 times smaller than the fourth number: 66/33 = 2
Based on this sequence, the sixth number would be 19 more than the fifth number. 33 + 19 = 52
