Write the sum using summation notation, assuming the suggested pattern continues. -8 - 3 + 2 + 7 + + 67

Remark: L = a + (n - 1)d is your starting point. In order to find the sum, you must know the value of n.

Givens: a = - 8; d=5; L = 67

Substitute and solve

67 = - 8 + (n - 1)*5 Add 8 to both sides.

67 + 8 = -8 + 8 + (n - 1)*5

75 = (n - 1)*5 Divide by 5 on both sides.

15 = n - 1 Add one to get the answer.

16 = n

Part Two: Use The summation notation to find the sum. Unfortunately, I don't know how to do this in latex.

Sum (n = 1 to 16) -8 + 5*(n - 1)

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
