a³ - 5a² + 4a + 5

Step-by-step explanation:

To solve this, remove the parentheses.  If you were subtracting the two phrases, you would distribute the negative sign to the second phrase, but you are adding so you will not have to do this

4a - a³ - 3 + 2a³ - 5a² + 8

a³ - 5a² + 4a + 5

We have the sequence that follows the pattern: a n = - 4 n + 13. If we want to calcelate the 14th term in this sequence ( or a 14 ), we have to substitute in this formula: n = 14. Then we will get: a 14 = - 4 * 14 + 13 a 14 = - 56 + 13, and finally: a 14 = - 43. The 14th term in the sequence is - 43.
