The data set below shows the number of books checked out from a library during the first two weeks of the month: 98, 19, 14, 15, 18, 16, 20, 22, 12, 17, 13, 21, 18, 15

Which of the following statements is true based on the data set? (1 point)

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.

wait nvm i know the correct answer now its 100%   81 square feet

~batmans wife dun dun

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.

step-by-step explanation:

is their an equation anywhere i can take a   look at it and see if i am right.
