B is the first term
c is the common ratio
if the first term is x and the 2nd is y then x times c=y
so
-5 times what=10?
what=-2
c=-2
the first term is -5
-5(-2)^(n-1)
b=-5
c=-2

monica
Step-by-step explanation:
Answer:
The correct answer is option c) y = 6
Step-by-step explanation:
It is given that|10-5y| =20
<u>Check each option</u>
a) y = 2
|10 - 5y| = |10 - 5 * 2| = | 10 - 10 | = 0 ≠ 20
b) y = 4
|10 - 5y| = |10 - 5 * 4| = | 10 - 20 | = |-10| = 10 ≠ 20
c) y = 6
|10 - 5y| = |10 - 5 * 6| = | 10 - 30 | = |-20| = 20
d) y = 10
|10 - 5y| = |10 - 5 * 10| = | 10 - 50 | = |-40| ≠ 20
From the above result we get the correct answer is option c) y = 6
