Answer:
see explanation
Step-by-step explanation:
In an arithmetic sequence the common difference d is
d = a₂ - a₁ = 10 - 8 = 2
To obtain the next term in the sequence add d to the previous term, that is
a₅ = 14 + 2 = 16
a₆ = 16 + 2 = 18
a₇ = 18 + 2 = 20
The next 3 terms in the sequence are 16, 18, 20
The n th term equation for an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 8 and d = 2, thus
= 8 + 2(n - 1) = 8 + 2n - 2 = 2n + 6
Answer:
Step-by-step explanation:
Given that,
He makes $10 per hour making sandwiches, and $14 per hour delivering orders.
Let there are s sandwiches and d is delivering orders.
Eric puts half of his total earnings in a savings account for college.
The expression that represents the total amount of money Eric saves for working s hours making sandwiches and d hours delivering orders.
Hence, this is the required solution.
