Step-by-step explanation:

There is a common difference d in the values, that is

9 - 5 = 13 - 9 = 17 - 13 = 21- 17 = 4

To obtain a term in the sequence add 4 to the previous term, thus

t₉ = t₈ + 4 → C

(b)

Given the n th term formula 3n - 8

To find any term, substitute the term position n into the formula

(i) first term (n = 1), then

3(1) - 8 = 3 - 8 = - 5

(ii) tenth term (n = 10, then

3(10) - 8 = 30 - 8 = 22

(iii) 100 th term ( n = 100), then

3(100) - 8 = 300 - 8 = 292

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.
