The correct answer to this problem is
C=3
Y=3
If the sequence is -4,-8,-16,.. then the seventh term be -256.
Given a sequence be -4,-8,-16,...
We are required to find the seventh term of the sequence.
If we carefully observe the sequence then we will find that the sequence is a geometric progression.
Geometric progression is a sequence which has a common ratio between all the terms.
Ratio of 2nd and 3rd term=-8/-4=2
Ratio of 3rd and 2nd term=-16/-8=2
Because the ratio is equal, so the sequence will be called a geometric progression.
Nth term of G.P=a
7th term=-4*
=-4*64
=-256
Hence if the sequence is -4,-8,-16,.. then the seventh term be -256.

Answer:
Congruent angles have the same angle.
Answer:
49 - 2y
Step-by-step explanation:
y to represent Vanessa's age.
49 decreased by twice Vanessa's age
decreased by means subtract, twice means 2 times
49 - 2y
