Answer:
d = 4
Step-by-step explanation:
The n th term of an arithmetic sequence is
 = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₁ = - 2 and a₈ = 26 , then
- 2 + 7d = 26 ( add 2 to both sides (
7d = 28 ( divide both sides by 7 )
d = 4

Answer:
-7
Step-by-step explanation:
(7 4/9 −8)∙3.6–1.6∙( 1/8 − 3/4 )+1 2/5 ÷(−0.35)
PEMDAS, parenthesis
-5/9∙3.6–1.6∙(1/8-6/8)+1 2/5 ÷(−0.35)
PEMDAS, division
-5/9∙3.6–1.6∙-5/8-4
PEMDAS, multiplication 
-5/9∙ 18/5– 8/5 ∙-5/8-4
-2-1-4
PEMDAS, subtraction
-7
