Answer:
= 3n + 4
Step-by-step explanation:
there is a common difference between consecutive terms , that is
10 - 7 = 13 - 10 = 16 - 13 = 3
this indicates the sequence is arithmetic with nth term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = 7 and d = 3 , then
= 7 + 3(n - 1) = 7 + 3n - 3 = 3n + 4
Answer:

Step-by-step explanation:
Given


Required
Represent the additional time needed as an inequality
Convert the previous time to minutes




Let the additional time be t
<em>This means that she needs to run at least t minutes to beat her previous record</em>
<em />
To beat her previous record, the sum of current time and x must be less than her previous time. i.e.

This can be rewritten as:
