Find the pattern then find the next term of the sequence. 5, 1, 7, 0, 9, -1, 11

5, 1, 7, 0, 9, -1, 11, -2, 13

Step-by-step explanation:

5, 1, 7, 0, 9, -1, 11

Two series in one:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
