The total number of 3 digit even numbers is 450
Step-by-step explanation:
Step 1 :
We need to determine the number of 3 digit numbers which is even and the leftmost digit is not zero .
The 3 digits with left most digit not equal to zero starts from 100 and goes up to 998
If we consider only the even 3 digit numbers in this interval, this would form an arithmetic progression with the first number a = 100 and the common difference d = 2.
Step 2:
The last number l in this series is 998 .
So we have
a = 100
l = 998
d = 2
The nth term in the arithmetic progression is given by a + (n-1) d
so substituting the above values we get
100 + (n-1) 2 = 998
2n = 900 => n = 450
Step 3 :
Answer :
The total number of 3 digit even numbers is 450
Answer:
f(1) = <u> 14000 </u>
f(n) = f(n - 1) · <u> 0.9 </u>, for n ≥ 2
The next term in the sequence is <u> 10206 </u>.
Step-by-step explanation:
First we try to find the type of sequence it is.
Is there a common difference?
12600 - 14000 = -1400
11340 - 12600 = -1260
There is no common difference, so it is not an arithmetic sequence.
12600/14000 = 0.9
11340/12600 = 0.9
There is a common ratio, so this is a geometric sequence.
Each term is 0.9 times the previous term.
The next term is:
11340 * 0.9 = 10206
Answer:
f(1) = <u> 14000 </u>
f(n) = f(n - 1) · <u> 0.9 </u>, for n ≥ 2
The next term in the sequence is <u> 10206 </u>.
Answer:
$927.12
Step-by-step explanation:
18.94×50 =$947 15%× 18.94=2.84 2.84×7 =19.88 947-19.88=927.12
