Answer:
55x^4+25x³+35x²
Step-by-step explanation:
Let's make an equation :
(4x²+8x-1 + 7x²-3x+8 ) ×5x²
(11x²+5x+7)×5x²
Now we put 5x² in front and expand :
5x²(11x²+5x+7)
55x^4+25x³+35x²
Hope this helped and have a good day
We have an initial term of 7 and a common difference of -2, so
a_n = 7 + -2(n-1) = -2n + 9
a_20 = -2(20)+9 = -40 + 9 = -31
