Answer:
21, 24, 29
Step-by-step explanation:
Replace n with 1, 2, and 3, and do the arithmetic.
first term = 1² +20 = 21
second term = 2² +20 = 24
third term = 3² +20 = 29
The first three terms are 21, 24, 29.
The answer would be 20%
If you subtract 450 and 360 you would get 90. So basically you do 90 divided by 450 and move the decimal point twice
Any two consecutive numbers can be written as
' X ' and ' X + 1 ' .
Their sum is [ x + (x+1) ] = 2x+1
You said the sum is 53, so
2x + 1 = 53
Subtract 1 from each side:
2x = 52
Divide each side by 2:
x = 26
The numbers are 26 and 27 .
X - 2 = 10
To solve for x add 2 to both sides of the equal sign:
X = 12
