These questions still confuse me greatly for some reason. i got the formula for it but i still don't know how to use it. , could someone explain it for me! write an equation for the nth term of the geometric sequence 896, -448, 224, find the eighth term of this sequence.

7/2

(decimal: 3.5)

welcome ; )

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:
