Write the nth term of the following sequence in terms of the first term of the sequence.
vovikov84 [41]

Givens

Sequence 2, - 4, 8, -16, 32 ....

First term = a = 2

Problem

Find the nth term

tn = (-1 )^(n -1) * (a)^n answer or

tn = (-1)^(n - 1) * 2^n

where a is defined as the first term (it usually is given that designation).

Try a few to make sure the formula is correct

<em>n = 1</em>

t1 = (-1)^(1 - 1) * 2^1

t1 = (-1)^0 * 2

t1 = 1 * 2 = 2

<em>n =2</em>

t2 = (-1)^(2 - 1) * 2^2 = (-1)^1 * 4 = -4

Expand can mean "To stretch or unfold." How can this definition help you remember this definition
mihalych1998 [28]
<span>There are several examples that can help one remember the definition of expand. To begin with, a balloon can expand when air or water enters it, depending on the type. Cookies often expand when baking due to the leavening agent used in the recipe. When we stretch our bodies, our muscles often expand.</span>

What are the steps to this equation to -2x-4+5x=8
laila [671]

Answer:

x = 4

Explanation:

−2x − 4 + 5x = 8

[ Simplify both sides of the equation ]

−2x − 4 + 5x = 8

−2x + −4 + 5x = 8

(−2x + 5x) + (−4) = 8 (Combine Like Terms)

3x + −4 = 8

3x − 4 = 8

[ Add 4 to both sides ]

3x − 4 + 4 = 8 + 4

3x = 12

[ Divide both sides by 3 ]

3x / 3 = 12 / 3

x = 4
