Find the indicated term of the given arithmetic sequence. a1=45, d= -3, n=10
2 answers:
In this sequence, we're given the first term, which is 45.
The difference between each term is -3, which means 3 will be subtracted in each term.
We're asked to find the value of the tenth term, and we can do so by using this formula:
a(n) = a(1) + d(n - 1)
Replace values.
a(10) = 45 + -3(9)
a(10) = 18
<h3>The value of the tenth term is 18.</h3>
Answer:
The tenth term = 18.
Step-by-step explanation:
The general form of arithmetic sequence Xn = a1 +(n -1)d
Given: a1 = 45, d = -3 and n = 10
Now plug in the given values in the general form to get the answer.
X10 = 45 + (10 -1)(-3)
X10 = 45 + 9*-3
X10 = 45 -27
X10 = 18
Therefore, the tenth term = 18.
Hope this will helpful.

Answer:
5/8
Step-by-step explanation:
well we 1 14/8 so lets turn that to a whole number which is 12/8 (you multiply the denominator by 1 and add the 4)
12/8 - 7/8 = 5/8 ( since both denominators are the same numbers you can simply subtract the numerator )
3 marbles as there is only one green and there is three other blue marbles left and that answer is incorrect

Answer:
range: {6, 1, -1}
Step-by-step explanation:
y = 4-x
when x = -2, y = 6
when x = 3, y = 1
when x = 5, y = -1
Answer:
∠a=40°
Step-by-step explanation:
complement of angle a=90-a
supplement of angle a=180-a
90-a=1/2(180-a)-20
multiply by 2
180-2a=180-a-40
180-180+40=-a+2a
a=40
