Write down in term of n an expression for the n th term of the following sequence a) 4,1,-2,-5,-8. b)-7,-12,-17,-22,-27

Step-by-step explanation:

a) a = 4; d =1-4 = -3

nth term = a + (n-1)*d

              = 4 + (n-1) * -3 = 4 -3n +3

nth term =7 - 3n

b) a = -7; d = -12 - (-7) = -12 + 7 = -5

nth term = -7 + (n-1) * -5

              = -7 - 5n + 5

              = -2 - 5n

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:
