I need help with this question someone please help and explain. Find the sum of the first twenty-seven terms of an arithmetic series whose first term is -8 and the sum of the first seven-term is 28.

Answers

Answer:

The sum of the first twenty-seven terms is 1,188

Step-by-step explanation:

we know that

The formula of the sum in arithmetic sequence is equal to

S=(n)/(2)[2a1+(n-1)d]

where

n is the number of terms

a1 is the first term

d is the common difference (constant)

step 1

Find the common difference d

we have

n=7

a1=-8

S=28

substitute and solve for d

28=(7)/(2)[2(-8)+(7-1)d]

28=(7)/(2)[-16+(6)d]

8=[-16+(6)d]

8+16=(6)d

d=24/(6)=4

step 2

Find the sum of the first twenty-seven terms

we have

n=27

a1=-8

d=4

substitute

S=(27)/(2)[2(-8)+(27-1)(4)]

S=(27)/(2)[(-16)+(104)]

S=(27)/(2)88]

S=1,188

Solve -7/3x - 3 = -52

Answers

x= 21

-rose (https://cherry-bomb03.webnode.com/)

Answer: x=21

Step-by-step explanation:

add 3 to both sides    -7/3x-3+3 = -52+3

simplify      -7/3x = -49

multiply both sides by 3            3(-7/3x) =3 (-49)

simplify            -7x=  -147

divide both sides by -7       -7x/-7 = -147/-7

then simplify         x=21

Someone please help.Describe the pattern that is being followed:
2, 4, 16, 256 . . .

What is the next number in the sequence?

Answers

The next number is 65536. The pattern is multiplying by itself to get the next number. So 2x2=4 4x4=16 and so on.
