Answer:

- 8

Step-by-step explanation:

The terms in an arithmetic sequence ar

a, a + d, a + 2d, ...... , a + (n - 1)d

Each term in the sequence is obtained by adding the common difference (d) to the previous term, that is

a₂ = 1

a₃ = a₂ + d = 1 - 3 = - 2

a₄ = a₃ + d = - 2 - 3 = - 5

a₅ = a₄ + d = - 5 - 3 = - 8

Answer:

-8

Step-by-step explanation:

Let the sequence be X.

Xn=a+(n-1)*d

where, n: nth term

a: first term

d: common difference

Given, X2=1

Then, 1=a+(2-1)*-3

or,a=1+3=4

So,X5=4+(5-1)*-3

or,X5=4+(4*(-3))

or,X5=4-12=-8

Express 7 square as the sum of two consecutive positive numbers.
Alborosie

Answer:

24 and 25

Step-by-step explanation:

From given, we have,

7 square = 49

Let the first positive number be = x

And the second consecutive positive number is = x+1

x + (x + 1) = 49

2x + 1 = 49

2x = 49 - 1

2x = 48

x = 24

the first number x = 24

the second consecutive number x+1  = 24 + 1 = 25

Thus, 7 square = 24 + 25 (the sum of two consecutive positive numbers.)

Gloria decides to buy 4 ferns, 2 Palms, 10 Lilies and 8 shrubs. To show the total
Vadim26 [7]

Answer:

Total Plants = 4F + 2P + 10L+ 8S

Total Plants = 2(2F + P + 5L+ 4S) --- Distributive property

Step-by-step explanation:

Given

Ferns = 4

Palms = 2

Lillies = 10

Shrubs = 8

Required

Show the total cost of plants as an expression

Shorten it using the distributive property

First, represent Ferns with F; Palms with P; Lilies with L and Shrubs with S;

So, 4 Ferns = 4F

2 Palms = 2P

10 Lilies = 10L

8 Shrubs = 8S

Total Plants = Summation of the above parameters

Total Plants = 4F + 2P + 10L+ 8S

The above expression represents the total plants bought;

Now, to apply the distributive property; we simply look for a common factor;

In this case, the common factor is 2;

So, Total Plants = 4F + 2P + 10L+ 8S becomes

Total Plants = 2(\frac{4F}{2} + \frac{2P}{2} + \frac{10L}{2}+ \frac{8S}{2})

Total Plants = 2(2F + P + 5L+ 4S)
