Find the sum of the arithmetic sequence.
-4, -1, 2, 5, 8, 11, 14

  35

Step-by-step explanation:

Since the sequence is so short, you can simply add the terms. It is convenient to do them pairwise, working inward from the first+last:

  (-4+14) +(-1+11) +(2+8) +5

  = 10 +10 +10 +5

  = 35

__

Or, you can find the average term as the average of the first and last terms:

  average term = (-4+14)/2 = 5

Then the sum is the product of this and the number of terms:

  sum = (number of terms)×(average term) = 7 × 5 = 35

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:

x=17
