Before using the Gizmo, consider an arithmetic sequence with a first term (a1) of 4 and a common difference (d) of 3. Challenge: What are the first five terms of the sequence (from lowest to highest)?

Step-by-step explanation:

The nth term of an arithmetic sequence is expressed as .

a is the first term of the sequence

d is the common difference

n is the number of terms

Given the first term a = 4 and common difference d = 3, we can calculate the first five terms of the sequence using the formula.

If n = 2

The first five terms of the sequence from lowest to highest are 4, 7, 10, 13 and 16

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:
