If he wants to earn $1000, it means that $1000 must be 20% of his overall sales.
1000 = 20% * x
1000 = 20/100x
1000 = 0,2x / ÷ 0,2 (both sides)
x = 5000
Answer: A salesman must sell products for $5000 to earn $1000.
Find an explicit formula for the arithmetic sequence -5,13,31,49,...−5,13,31,49,...minus, 5, comma, 13, comma, 31, comma, 49, co

Answer:
aₙ = a₁ + (n-1) * 18 a₁ = -5
Step-by-step explanation:
aₙ = a₁ + (n-1) * d a₁ = -5 d = 13 - (-5) = 18
a₂ = -5 + (2 - 1) * 18 = -5 + 18 = 13
a₃ = -5 + (3 - 1) * 18 = -5 + 36 = 31
a₄ = -5 + (4 - 1) * 18 = -5 + 54 = 49
