Answer:
21, 28, 36
Step-by-step explanation:
1 + 2 = 3
3 + 3 = 6
6 + 4 = 10
10 + 5 = 15
Next three terms,
15 + 6 = 21
21 + 7 = 28
28 + 8 = 36.
Answer:
X = -1
Step-by-step explanation:
f(-1) = 6(-1) + 1
6 * -1 = -6
-6 + 1 is equal to -5
I hope this helps (:
If the roots are 1 and 3, the factors of this quadratic are (x-1) and (x-3).
The polynomial is x^2 - 4x + 3.
If you were supposed to write a polynomial based upon all four given roots, then:
Looks as tho' you have four distinct roots. The 4th order polynomial with these roots is f(x) = (x-1)(x-3)(x-7)(x-2). Multiply this out, combine like terms and then arrange the terms in descending order by powers of x.
From the given, it can be seen that the quotient obtained when second term is divided by the first term is equal to 4. This is the same answer when the third term is divided by the second term. Finally, the same quotient when the last term is divided by the third term. This means that the values progress with a common ratio. Thus, the answer is geometric.
