X^2=10
square root it
sqrt(x^2) = sqrt (10)
x= sqrt(10)

First we need to determine the type of progression in the question.That's geometric progression. Because the pattern from one sequence to the others are about multiplying.
Second, determine the ratio of the progressionr = a₂/a₁
r = a₂ ÷ a₁
r = 1/2 ÷ 2
r = 1/2 × 1/2
r = 1/4
Third, determine the formula to know the recursive rulea₂ = a × 1/4
a₂ = 1/4 × a
Fourth, determine a₁. a₁ is the first term of the progressiona₁ = 2
Final answer:Recursive rule

a₁ = 2
The exponent only applies to the x not the 4
so only the x has permission to move to the denominator
this leaves you with 4/x^3
The angles look like

F- angles are corresponding angles.
Corresponding angles are congruent.
