URGENT The boxplot below displays the arm spans for 44 students.
A boxplot. A number line labeled arm span (centimeters) goes from 140 to 210. The whiskers range from 142 to 202, and the box ranges 162 to 180. A line divides the box at 168.

The five-number summary for the data is 143, 162, 168, 180, and 202.

Which of the following is not a true statement?

Approximately 75% of the arm spans are less than 180 cm.
Approximately 50% of the arm spans are less than 168 cm.
Approximately 25% of the arm spans are less than 180 cm.
Approximately 75% of the arm spans are greater than 162 cm.

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
