The question is in the picture

Step-by-step explanation:

For the first question

The missing term is 30

because 5 is being added to every term .

So last known term is 25 and by the sequence we can see that 5 is being added to the last term to make the next one

25+5=30

For the second: Pay attention

Let's say you want to find the nth term of the sequence. (Eg. what will be the 50th number of the series just like 10 is the 1st term of the sequence)

For nth term the formula is :

An= d.n+a1-d

where d is the difference '5' in this case

n is the nth term

a1 is the first term (10 in your case) and again d is the difference of number which is 5

so

an=5n+5 (by substituting values)

now for finding 100th term put 100 in place of n

a100=5(100)+5

a100=505

100th term is 505

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29

i believe it's a.

i'm not sure on this one, most likely correct.
