This would be the difference of perfect squares.
x^2 - 9
(x - 3) (x + 3)
It is a <span>Fibonacci Sequence:
So the missing number is 5 + 8 = 13</span>
That's right very good
but its better to write (x+5)²instead of (x+5)(x+5)
1) 50*50, our 2500
2) 1500
3)1500
4) 900
just multiply t the number of people by the amount each pays
Since the sequence has a common difference of 5, hence the sequence is 4, 9, 14, 19, ... is defined recursively using the formula f(n 1) = f(n) – 5 .
<h3>Recursive functions</h3>
Recursive functions are functions used to generalize sequence. Given the recursive function
f(n - 1) = f(n) – 5 .
This can be written as:
f(n) - f(n-1) = 5
This shows that the correct sequence must have a common difference of 5
For the sequence 4, 9, 14,19...
d = 9 - 4 = 14 - 9
d = 5
Since the sequence has a common difference of 5, hence the sequence is 4, 9, 14, 19, ... is defined recursively using the formula f(n 1) = f(n) – 5
