Answer:
c 1, 2, 4, 8
Step-by-step explanation:
It can work well to look at the first differences.
a: 4 -2 = 2; 6 -4 = 2 ⇒ differences are 2, 2, 2
b: differences are 0, 1, 1
c: differences are 1, 2, 4
d: differences are 2, 2, 2

Sequences 'a' and 'd' have common differences that are constant. These are arithmetic sequences. Sequence 'b' is of no named type.
Sequence 'c' has first differences that have a common ratio, the same as the sequence itself. This is an indication the sequence is geometric. The ratios of values are 2/1 = 2; 4/2 = 2; 8/4 = 2, so the terms have a common ratio.
Sequence c is a geometric progression.

Answer:
5/6 cups of chocolate chips
Step-by-step explanation:
According to a recipe , 2 1/2 * c * u * p chocolate chips are needed to make a large batch of cookies. Manuel decided to make only 1/3 of the cookies . How many cups of chocolate chips will Manuel need ?
From the above question:
1 batch of cookies = 2 1/2 cups of chocolate chips
1/3 batch of cookies = x
Cross Multiply
x = 1/3 × 2 1/2
x = 1/3 × 5/2
x = 5/6 cups of chocolate chips
Hence, Manuel would need 5/6 cups of chocolate chips for 1/3 bath of cookies.
