Answer:
If they have the same variable you add or subtract them.
Step-by-step explanation:
Add the x's
SO 3x=18
divided by 3
So x=3
24 un the eighth row im sure of it because it adds my 3 each time if you look at the 1st row it says 15 then it adds by another 3 to 18 and then to 21
Answer:
The 9th term is 17179869184
Step-by-step explanation:
Here we have that;
The divisors of 1 = 1 which is 1 less than 1*2
The sum of the divisors of 2 = 1 + 2 = 3 which is 1 less than 2*2
The sum of the divisors of 4 = 1 + 2 + 4 which is 1 less than 4*2
The sum of the divisors of 8 = 1 + 2 + 4 + 8 which is 1 less than 8*2
The sum of the divisors of 32 = 1 + 2 + 4 + 8 + 16 + 32 which is 1 less than 32*2
The sum of the divisors of 256 = 1 + 2 + 4 + 8 + 16 + 32 + 64 + 128 + 256 which is 1 less than
The next numbers are therefore,
32 × 256 = 8192
256 × 8192 = 2097152 and the 9th term is therefore;
8192 × 2097152 = 17179869184.
