What is the 17th term in the arithmetic sequence in which a6 is 101 and a9 is 83

Alina fully simplifies this polynomial and then writes it in standard form. xy2 – 2x2y + 3y3 – 6x2y + 4xy2 if alina wrote the last term as 3y3, which must be the first term of her polynomial in standard form? xy2 5xy2 –8x2y –2x2y

If t8 = 4 and t12 = −2, find the first three terms of the arithmetic sequence.
