It's forming an A. P. because each succeeding Te rm increases by a common value i. e. 6 here.

The A. P is

22,28,34,.....

So the n th term will be represented as

a+(n-1)d,

where a=22

And d=6

Now in (b) part the n th term is given i. e. 100

So by putting in the given values we could easily found the value of n

n=(100-22)/6=78/6=13

So the 13th term will be 100

Hope You Got It.

1. 4<7 Multiply both sides by 7, then by 6, then by 3, then by 10
erastova [34]

What is 4.3(v+2.5)=8.11+4v
True [87]

Answer:

-8.8

Step-by-step explanation:

We begin by simplifying the parenthesis through multiplication. Parenthesis is a structure which signals multiplication happening.

4.3(v+2.5)=8.11+4v\\4.3v+10.75=8.11+4v

We now begin combining like terms across the equal sign by performing the inverse or doing the opposite. Move first the 8.11 by subtracting it from both sides.

4.3v+10.75-8.11=8.11-8.11+4v\\4.3v+2.64=4v

Now, move 4.3v across by subtracting it from both sides.

4.3v-4.3v+2.64=4v-4.3v

2.64=-0.3v

Finally, we divide both sides by the coefficient of v.

\frac{2.64}{-0.3} =\frac{-0.3v}{-0.3} \\-8.8=v

How is the scientific use of the term digital different from the common use
Mamont248 [21]
While “digital” commonly refers to electronics in general, the scientific definition of digital is much different. “Digital” in information science refers to the finite, discontinuous phenomenon (e.g., on or off states in a light bulb) as opposed to infinitely varying, continuous analog phenomenon (e.g., the brightness of daylight). It can also refer to representing data in figures as opposed to data represented in pictorial form.
