Which of the following recursive formulas represents the same arithmetic sequence as the explicit formula an=-2+(n-1)3

and

Step-by-step explanation:

The terms of an arithmetic sequence are given by the formula

So, the first term,

The second term,

The third term,

And the fourth term,

So, from the terms of the A.P. sequence, it is clear that,

and

Therefore, this is the recursive formula of the given arithmetic sequence. (Answer)

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
