Answer:
21,42,84,168,336,672, 1,344
Step-by-step explanation:
The pattern is to multiply the previous term by 2 to find the next term. The seventh term should be 1,344.
Answer:0.004
an= a1(r) ^ n-1
a7= 1(2/5) ^6
BOA
angle COB = 80 - 60 = 20
angle BOA = 60 - 40 = 20
.
To solve this problem, we need to simplify the expression .
We know that
Therefore:
