3 9 4 5 25 20 21 441 ?
32=99-5=44+1=552=2525-5=2020+1=21212=441
That question is unanswerable.

You seem to be unaware of the fact that you could have obtained the answer much more easily and quickly by using the calculator that comes as part of your computer. sqrt(441/625) = sqrt(441)/sqrt(625) = 21/25 = 0.84
To find the common difference in the arithmetic sequence, we can use the formula for the nth term of an arithmetic sequence: (a_n = a_1 + (n-1)d), where (a_n) is the nth term, (a_1) is the first term, (n) is the term number, and (d) is the common difference. Given that 24 is the fifth term in a sequence of 10 numbers, we can set up the equation (24 = a_1 + 4d). We also know that there are 10 terms in the sequence, so the 10th term can be expressed as (a_{10} = a_1 + 9d). With this information, we can set up a system of equations to solve for the first term (a_1) and the common difference (d).

436 is the best choice for the next number in the sequence because:3x3=9-5=45x5=25-5=2021x21=441-5=436The Pattern: Square the term, then take away 5, add one, and square it again, and so on.
25 is the next number that appears in that sequence.
