Recursive Sequence
We are given the following sequence:
-1, 1, 5, 13...
It's required to find the recursive term for the sequence.
A recursive formula calculates each term as a function of one or more previous terms.
To find the recursive formula, we must find a pattern and transform it into a math expression.
Let's write the sequence, and below it, the difference of consecutive terms:
-1, 1, 5, 13...
+2, +4, +8
Note the difference between consecutive terms is always a power of 2, starting from 2^1, 2^2, 2^3.
The exponent is one less than the number of the term, thus:
Thus:

Answer:
31.925 ft
Step-by-step explanation:
A diagram is needed to visualize Dylan's movement to Alex see below
thus (-22.4)² + y² = 26²
y² = 26² - (22.4)² = 174.24
y = -√174.2 = - 13.2 ft note due south
closest point at intersection
3/11* ( x- 26) = -11/3 x * + 26
3/11 x - 78/11 = -11/3x + 26
3/11 x +11/3x = 26 + 78/11
130/33 x = 364/11
x = 364/11 * 33/130 = 8.4
then y = 3/11 * (x -26)
x = 8.4 substitute, gives y = 3/11 * (8.4 -26) = -4.8
distance from (8.4 , -4.8) to (0 , 26)
√[(0 -8.4)² + ( 26-(-4.8))² ] = √[( -8.4)² + ( 30.8)² ] = 31.925 ft
