So you're adding 3, 5, 7, 9, 11 etc 1, 4, 9, 16, 25, 36, 49
the next number in the sequence is 25............starting at the beginning, you add the odd numbers to the existing number to get the answer. Add "1" to 0, get 1; add "3" to 1, get 4; add "5" to 4, get 9; add "7" to 9 to get 16........and add "9" to 16 to get 25.........
n2
This is a sequence of perfect squares. 12=1, 22=4, 32=9, 42=16, 52=25. The next number is 62=36.
These look like a series of squares.1 squared is 1, 2 squared is 4, 3 squared is 9, 4 squared is 16, 5 squared is 25 and then 6 squared is........36.
4x+9=25 4x+9=25-9 4x/4=1 16/4=4 4x+9=26 4(4)+9=25 16+9=25 The answer is 4
The factors of 9 are: 1, 3, 9 The factors of 16 are: 1, 2, 4, 8, 16 The factors of 25 are: 1, 5, 25
There are many options: 1 + 1 + 1 ... (45 times) 1 + 1 + 1 ... (9 times) + 4 + 4 + 4 ... (9 times) 4 + 4 + 4 + 4 + 4 + 25 1 + 1 + 1 + 1 + 4 + 4 + 4 + 4 + 25 1 + 1 + 9 + 9 + 25 4 + 16 + 25 1 + 1 + 1 + 1 + 16 + 25 and what you were probably looking for but did not specifically ask for, 9 + 36
add 3,5,7,9and then to 25 add 11, adding odd numbers onto the last . 1+3=4, 4+5=9, 9+7=16, 16+9=25, 25+11=36 and so on
1, 4, 9, 16, 25, 36
26
They are: 1, 4, 9, 16 and 25
The median is the middle of the list (when sorted). In this case 16. The sorted list is:1, 4, 9, 16, 25, 36, 49.
It is: 1
1, 4, 9, 16, 25, 36
So you're adding 3, 5, 7, 9, 11 etc 1, 4, 9, 16, 25, 36, 49
The greatest common factor (GCF) of 9, 16, and 25 is 1 The factors of 9 are: 1, 3, 9 The factors of 16 are: 1, 2, 4, 8, 16 The factors of 25 are: 1, 5, 25 The common factors are: 1 They're all squares of prime numbers
