Answer:
= 10 - 3n
Step-by-step explanation:
the terms 7, 4, 1, - 2 form an arithmetic sequence with n th term
=
+ (n - 1)d
where d is the common difference and the first term
here d = - 2 - 1 = 1 - 4 = 4 - 7 = - 3 and = 7, hence
= 7 - 3(n - 1) = 7 - 3n + 3 = 10 - 3n
Mrs Wright's paycheck was $ 630
<u>Solution:</u>
Given that,
Mrs Wright spend on food =
Fraction spent on rent =
She spent 1/4 of the remainder on transportation
Remaining left with her = $ 210
Let the paycheck amount be "n"
Now, we know that, paycheck amount = used amount + left over amount
Here, left over amount = 210
Paycheck amount = 2/9 of paycheck on food + 1/3 of paycheck on rent + 1/4 of remainder on transportation + 210
Upon simplifying we get,
On simplification, we get
On adding fractions we get,
Hence, the paycheck amount is $630
