A,3x+2,b form an arithmetic sequence. if the common difference is 2x - 1 , what is A equal to?

a is equal to x + 3

Step-by-step explanation:

Arithmetic Sequences

The arithmetic sequences are identified because any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.

We are given the sequence:

a, 3x+2, b

And the common difference is 2x-1

Subtracting the second and the first terms:

3x + 2 - a

We can find the common difference since it's given:

3x + 2 - a = 2x - 1

Solving for a:

- a = -3x - 2 + 2x - 1

- a = -x - 3

a = x + 3

a is equal to x + 3

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
