Classify each sequence as arithmetic, geometric, or neither by dragging it into the correct box

 -4,-2,1,4,8,... it is neither arithmetic nor geometric

-1,3,7,11,15,... it is Arithmetic

36,12,4,4/3, 4/9,... it is Geometric

Step-by-step explanation:

-4,-2,1,4,8,...

When sequence is arithmetic then the difference between two terms should be same

When sequence is Geometric then the ratio of two consecutive terms should be same

-2-(-4) = 2

1-(-2) = 3

correct answer:

i^31 = -i

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
