Consider the following sequence 152, -76, 38, -19
Write a rule for the nth term and then find

a₇ =  2.375

Step-by-step explanation:

There is a common ratio r between consecutive terms, that is

r = = = = -

This indicates the sequence is geometric with nth term

= a₁

where a₁ is the first term and r the common ratio

Here a₁ = 152 and r = - , then

= 152 , so

a₇ = 152 = 152 × = 2.375

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
