What are the 3 previous term in the sequence? 5, -2, -9, -16, -23

  12, 19, 26

Step-by-step explanation:

Each new term in the sequence is found by subtracting 7 from the previous term. So, each previous term can be found by adding 7 to the one you have.

The three previous terms (working backward) are ...

  5+7 = 12

  12+7 = 19

  19+7 = 26

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
