Write the first five terms of the sequence in which the nth term is an=(n+1)! / n+1

goblinko [34]

Answer:

1, 2, 6, 24, 120

Step-by-step explanation:

let's work on each of the five terms requested for the sequence. Notice that the first term is when we give n the value 1 $a_1=(1+1)!/(1+1)=2!/2=2/2=1$

Next term (when n=2) is: $a_1=(2+1)!/(2+1)=3!/3=3*2/3=2$

Next term (when n=3) is: $a_1=(3+1)!/(3+1)=4!/4=4*3*2/4=6$

Next term (when n=4) is: $a_1=(4+1)!/(4+1)=5!/5=5*4*3*2/5=24$

Next term (when n=5) is: $a_1=(5+1)!/(5+1)=6!/6=6*5*4*3*2/6=120$

Consider the function f ( x ) = 1 − 4 x 2 on the interval [ − 1 , 3 ] . Find the average or mean slope of the function on this i

Blababa [14]

Answer:

The average slope is 8.

Step-by-step explanation:

Let f be defined on the closed interval [a, b]. The average slope of f between a and b is the quotient

average slope = $\frac{f(b)-f(a)}{b-a}$

To find the average slope of the function $f(x)=1-4x^2$ on the interval [-1, 3] you have to evaluate your function in the interval and then divide by the interval.
