Margo has a coin collection. she was given 1 coin as a gift, and she adds 3 coins per year. which of the graphs below represents margo's coin collection? graph of line going through 1, 2 and 3, 4 graph of line going through 1, 1 and 3, 3 graph of line going through 1, 4 and 3, 10 graph of line going through 1, 2 and 2, 5

The graph that represents Margo's coin collection is:

      Graph of line going through (1, 4) and (3, 10).

It is given that:

She was given 1 coin as a gift, and she adds 3 coins per year.

Let a_n denote the amount of Money Margo had in the end of the "nth" year.

According to the given information we have:

and so on.

Hence, we get:

Hence, we get a Arithmetic progression.

with first term as 4 and common difference as 3.

Hence, the graph is:

Graph of line going through (1, 4) and (3, 10).

( Since at n=1 we have:

and at n=3 we have:  )

step-by-step explanation:

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
