For Exercises 1 and 2, refer to the figure, which shows
a utility pole with an electrical line and a telephone
line. The angled wire is a tension wire. Assume that
the electrical line and the telephone line are
perpendicular to the utility pole. (For these exercises.
you may think of the utility polo as a line.)

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
