The rule to calculate the a_n term in an arithmetic sequence is
where
d is the common difference
a_1 is the first term
n is the number of terms
we have
Remember that In an Arithmetic Sequence the difference between one term and the next is a constant. and this constant is called the common difference
so
Find the 96th term of the arithmetic sequence
we have
substitute
Answer: 20 feet
Step-by-step explanation:
This represents a right angled triangle with the length of the slide being the hypotenuse, the height of the ladder being the height of the triangle and the distance from the base of the ladder being the length.
Solve with Pythagoras rule:
c² = a² + b²
c = hypotenuse
a= length
b = height
29² = 21² + b²
841 = 441 + b²
b² = 841 - 441
b² = 400
b = √400
b = 20 feet
