Answer:
20
Step-by-step explanation:
ii) 7, 12, 17, 22..
The difference between the i) pair is 3, and the ii) pair is 5.
So ,
17 + 3 = 20.
22 + 5 = 27.
Therefore the series is 8, 7, 11, 12, 14, 17, 17, 22, 20, 27.
Given that the last term is -3x^4, the polynomila is ordered in descending order of the exponent of x. Then, the first term is that where y is with the highest exponent, that is y^4
Simplify the terms with y^4: -2y^4 + 6y^4 = 4y^4
Then the first term is 4y^4
