Answer:
perimeter of a rectangular swimming pool is 154 m. Its length is ... 2x + 3x + 3 + 4x + 8 = 74. => 9x + 11 = 74. => 9x = 74 – 11. => 9x = 63 ... Solve the following equations and check your results: 2x/3 + 1 = 7x/15 + 3.
Answer:

Step-by-step explanation:
We are given the recursive formula:

This is the recursive formula for an arithmetic sequence.
The explicit formula for an arithmetic sequence is given by:

Where d=3 is the common difference.
We plug in this values to get:

We now expand and simplify to get:

We simplify to obtain:

The answer is 121. Hope that helped :)
