Which of the following are explicit equations for the nth term of some kind of arithmetic sequence? a) pn=p1+(n-1)p1 b) an=an-1+d c) xn=x1(n-1) d) xn=xn-1+vt e) pn=pn-1+ip1

The required equation is

Step-by-step explanation:

To find : Which of the following are explicit equations for the nth term of some kind of arithmetic sequence?    

Solution :

The Explicit formula which shows the nth term of a sequence in terms of n is given by,

Where, is the nth term

is the first term

n is the number of terms

d is the common difference

Therefore, The required equation is

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
