The difference of 9 times a number and 2 is 67.Which equation below can be used to find the unknown number?

Answers

Answer 1

Answer: the total is 67 so you would write that out
67=
Next you can write out 9 times a number. you can let that unknown number be n(you can use any variable you like). So now you would have
67=9n
You still have to subtract 2 from the 9n so plug that in
67=9n-2
Your answer would be 67=9n-2

What is the 23rd term of the arithmetic sequence where a1 = 8 and a9 = 48?

Answers

Answer:

23rd term of the arithmetic sequence is 118.

Step-by-step explanation:

In this question we have been given first term a1 = 8 and 9th term a9 = 48

we have to find the 23rd term of this arithmetic sequence.

Since in an arithmetic sequence

$T_(n)=a+(n-1)d$

here a = first term

n = number of term

d = common difference

since 9th term a9 = 48

48 = 8 + (9-1)d

8d = 48 - 8 = 40

d = 40/8 = 5

Now $T_(23)= a + (n-1)d$

= 8 + (23 -1)5 = 8 + 22×5 = 8 + 110 = 118

Therefore 23rd term of the sequence is 118.
