Answer:
34 + 8n
Step-by-step explanation:
a₁ = 42
a₂ = a₁ + 8 = 42 + 8 = 50
a₃ = a₂ + 8 = 50 + 8 = 58
a₄ = a₃ + 8 = 58 + 8 = 66
Arithmetic sequence: 42, 50 , 58 , 66, ......
a₁ = 42 ; d = 8
= a₁ + d(n-1)
= 42 + 8(n - 1)
= 42 + 8n - 8
= 34 + 8n

Ted’s basket contains = 5 apples
Weight of each apple in Ted’s basket = 7 1/4 ounces
Robin’s basket contains = 6 apples
Weight of each apple in Robin’s basket = 6 1/2 ounces
<u>To Find:</u>
Whose basket is heavier and by how much?
<u>Solution:</u>
<u>Step 1: Finding the weight of Ted’s basket </u>
Weight of Ted’s basket = Number of apple in the basket X Weight of each apple
Weight of Ted’s basket =
Weight of Ted’s basket =
Weight of Ted’s basket =
Weight of Ted’s basket = 36.25 --------------------------------(1)
<u>Step 2: Finding the weight of Robin’s basket </u>
