Answer:
The nth term of the given sequence
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given sequence -5,-4,-1,4,11,20,31
a₀ = -5
a₁ = a₀ +1 = -5 +1 = -4
a₂ = a₁ + 3 = -4+3 = -1
a₃ = a₂ + 5 = -1 +5 = 4
a₄ = a₃ + 7 = 4 + 7 =11
a₅ = a₄ + 9 = 11+9 = 20
a₆ = a₅ + 11 = 20+11 = 31
a₇ = a₆ + 13 = 31 +13 =44
and so on
The nth term of the given sequence
Answer:
x=2 is the only solution
Step-by-step explanation:
The given expression is;
Add 1 to both sides of the equation;
Square both sides ;
This implies that;
Split the middle term
x=-3,or x=2
Check for extraneous solutions by substituting into the original equation.
When x=-3,
This is an extraneous solution.
When x=2,
. This is true
This is not an extraneous solution
