The answer is A
Reasoning;
<span>a1 = first term;
an</span><span>= </span>a<span>n-1</span><span> + </span><span>d
</span>In a sequence you add the first term (a1) with the second term in a repeating linear equation. In this one you need to add 4 to each term so, the equation is;
a1 = 2
an = an -1 + 4

Answer:
A.
Step-by-step explanation:
x2 - 3x - 10. = 0
x2 + 2x - 5x - 10 = 0
(x2 + 2x) (-5x - 10) = 0
x (x + 2) - 5 (x + 2) = 0
(x - 5) (x + 2) = 0
x - 5 = 0 x + 2 = 0
x = 5 or x = - 2.
3x (x + 2)²
3x ( x² + 4)
3x³ +12x
