Find the 4th term in the sequence with the following definition: a1=-2 an an=2an-1-3

Mathematics
1 answer:
Alexus [3.1K]3 years ago
7 0

Answer:

The 4th term is -37.

Step-by-step explanation:

The first term of the series is

a_1=-2,

the second term of the series is

a_2 =2a_1-3

a_2=2(-2)-3\\\\a_2=-7,

the third term is

a_3 = 2a_2-3

a_3=2(-7)-3

a_3=-17,

and the fourth term of the series is

a_4=2a_3-3\\

a_4=2(-17)-3

\boxed{a_4=-37}

The length of a rectangle is five times it’s width. If the perimeter of the rectangle is 120 yd, find it’s area
natita [175]

Answer:

Because the Length is 5 times the width, L(length) = 5w. You can use this information to update your perimeter.

P= L + W

P= 5w + w = 6w

P = 120, 120= 6w

120/6 = 6w/6

20 = w

L = 5w, L = 5(20) = 100

A = L x W, 100 x 20 = 2000

This means 2000 is the area

A geometric sequence has a first term of x-y and a common ratio of x+y. what if the third term of the sequence?
kotegsom [21]
First term t(1)=(x-y)
common ratio =(x+y)  (don't omit the parentheses)
then the nth term:
t(n)=(x-y)(x+y)^(n-1)
check:
t(1)=(x-y)(x+y)^(1-1)=(x-y)(x+y)^0=(x-y)(1)=(x-y)
t(3)=(x-y)(x+y)^(3-1)=(x-y)(x+y)^2

When n is small, t(n) can also be found by repeated multiplication of the common ratio (x+y)
