Asequence is defined recursively using the formula f(n + 1) = f(n) – 5 . which sequence could be generated using this formula?

1, –5, 25, –125,
2, 10, 50, 250,
3, –2, –7, –12,
4, 9, 14, 19,

Step-by-step explanation:

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

answer:

it is 28 degrees colder in detroit than philadelphia.

step-by-step explanation:

what number adds to 21  

-7 + ? = 21

-7 + 28 = 21
