REASONING A student claims that the next number in the pattern 1, 2, 4, ... is 8, because each number shown is two times the previous
number. Is there another description of the pattern that will give the
same first three numbers but will lead to a different pattern? Explain.

Step-by-step explanation.

Explanation:

Each number is the same as 1 plus the numbers before it.

2 is 1 + 1

4 is 1 + 1 + 2

7 is 1 + 1 + 2 + 4

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

the correct answer is c
