What is the explicit formula for this sequence?
SVEN [57.7K]

Answer:

The correct answer is b.)

Step-by-step explanation:

Given:

Sequence  -7, -4, -1, 2, 5.......  => a₁ = -7, a₂ = -4, a₃ = -1, a₄ = 2 and a₅ = 5

We conclude that this sequence is arithmetic series.

First we must find difference d:

d = a₂ - a₁ = a₃ - a₂ = -4 - (-7) = -1 - (-4) = -4 + 7 = -1 + 4 = 3

d = 3

The formula for n-th term of the arithmetic series is:

aₙ = a₁ + (n-1) d

aₙ = -7 + (n-1) 3

God with you!!!

An employee’s new salary is $26.355 after getting a 5% raise. What was the salary before the increase pay?
Serga [27]

Answer:

$25.03725

Step-by-step explanation:

<u>Step 1:  Multiply both sides by %5 to get the raise</u>

26.355 * %5 is same as 26.355 * 0.05

$1.31775 is the raise

<u>Step 2:  Subtract the raise from the new salary</u>

26.355 - 1.31775

25.03725

Answer:  $25.03725

I need help on finding the area of a parallelogram
Hoochie [10]

Answer:

1. 540 sq. ft.   2. 7,200 sq. m.   3. 276 sq. yd.   4. 6,000 sq. mm.

Step-by-step explanation:

You find the area of a parallelogram by doing the same as you would a rectangle, multiplying length by width. (If you imagine slicing off the triangle shape on the end of all of these and putting it on the other side, it will always make a rectangle.)
