Answer:

671 is the 224th term of the given series

Step-by-step explanation:

The given sequence is

2,5,8,11....

First term that is 2

common difference that is 3

we have to find 224th term

That is n =224

using $a_n=a+(n-1)d$

$a_{224}=2+(224-1)3$

On solving the above equation we get

$a_{224}=671$

Hence, 224th term of the given series is 671

The equation is c=85x+60 how do you solve for x?

Yakvenalex [24]

Solve for x.
c=85x+60

Flip the equation.

85x+60=c

Add -60 to both sides.

85x+60+−60=c+−60

85x=c−60

Divide both sides by 85.

85x/85=c−60/85

x = 1/85 c + −12/ 17
