Given the following sequences state the next number 1, 18, 16, 32 1, 1, 2, 3, 5, 8, 13, 21
-26, -15, -4, 7
256, 225, 196, 169,

Not sure about the 1st sequence

Second sequence: 34

Third sequence: 18

Fourth sequence: 144

Step-by-step explanation:

The second sequence is the Fibonacci sequence. You find the next term by adding to two previous terms, so you have 13+21 which is equal to 34.

The third sequence is an arithmetic sequence that has a common difference of 11. Knowing this, we can add 11 to the last term to find the next one. This gives us 7+11 which is 18

The third sequence is the square of numbers starting form 16 and decreasing by one each time. This can be written with the formula =, where n is the term of the sequence you are solving for. Since you need to solve for the fifth term of the sequence the equation becomes, = which is the same as , so the 5th term is 169.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
