10, 4. -2, -8 in an explicit formula

16 - 6n

Step-by-step explanation:

10 , 4 , -2 , - 8

This is arithmetic sequence

first term = 10

Common difference = 2nd term - first term

                          d    = 4 - 10

                            d = -6

nth term = a₁ + (n -1)d

              = 10 + (n - 1)*(-6)

             = 10 + n*(-6) - 1*(-6)

             = 10 - 6n + 6

             = 10 + 6 - 6n

             = 16 - 6n

hi there!

the answer is: 2 and -2

step-by-step explanation:

case 1: an absolute value of positive number will still be a positive number

so absolute value of 2 is 2

case 2: an absolute value of negative number will be positive number so absolute value of -2 is 2
