A sequence<span> is a set of numbers.
</span>If the difference between two consecutive terms is constant, then the sequence is called arithmetic and th<span>e difference is called the common difference.
</span><span>If the numbers in the sequence follow a pattern were the next term is found by multiplying by a constant called the common ratio, r, then the sequence is geometric sequence.</span>
Answer:

Step-by-step explanation:
ill suppose that you mean : "solve for b" not for d, since there is no d term in the formula given. So:

Answer:
Step-by-step explanation:
Here you go mate
Use PEMDAS
Parenthesis,Exponent,Multiplication,Division,Addition,Subtraction
Step 1
4n-9=2(5+2n) Equation/Question
Step 2
4n-9=2(5+2n) Remove parenthesis
4n-9=4n+10
Step 3
4n-9=4n+10 Subtract 4n to sides
-9=10
Step 4
-9=10 Add 9
0=19

The answer is 2x^2-3x-2.
To solve this, you take f(x)-g(x) which is 2x^2-5-3x+3. This simplifies to 2x^2-3x-2.
