Which infinite sequence is generated by the formula an = (–2)n?
–2, –4, –8, –16, –32,
–2, 4, –8, 16, –32,
2, –4, 8, –16, 32,
2, 4, 8, 16, 32,

–2, 4, –8, 16, –32, ...

Step-by-step explanation:

aₙ = (-2)ⁿ

a₁ = (-2)¹ =    -2

a₂ = (-2)² =    4

a₃ = (-2)³ =   -8

a₄ = (-2)⁴ =   16

a₅ = (-2)⁵ = -32

Each term has a factor of (-1)ⁿ. Thus, odd-numbered terms are negative, and even-numbered terms are positive  

The series is –2, 4, –8, 16, –32, ...

answer B

Step-by-step explanation:

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

it should be a.
