It’s 3840. The pattern is multiply by 2 then 4 then 6 then 8 then 10, … .... Show More
11×2 = 22×4 = 88×6 = 4848×8 = 384384×10 = 384012×3480 = 41760This can be written as either of the following:(2n)!! (2^n) n!Note that !! does not mean to do factorial twice. The ! means factorial. !! means something called "double factorial."So for n=5 (what you want), put:(2^5) 5!= 32 × (5 × 4 × 3 × 2 × 1)= 32 × 120 = 3480Double factorial is where you take every other one. For n=5, we can do:(2×5)!! = 10!!= 10 × 8 × 6 × 4 × 2notice we take every other factor as we count down from 10 = 3480Which also demonstrates how this recursion actually defines the !! function....

2 x 1 = 24 x 2 = 86 x 8 = 488 x 48 = 34810 x 348 = 348012 x 3480 = 41,760... Show More
38401*2 = 22 *4 = 88 * 6 = 4848 * 8 = 384 384 * 10 = 3840thus multiply it times 10 to get 3840... Show More
Appears to be successive multiples of 2, so 10 x 384 = 3840... Show More
3840…each subsequent number is being multipied by the next number counted by two.1 (x2) 2 (x4) 8 (x6) 48 (x8) 384 (x10) 3840.... Show More
3840 You are multiplying each term by,then 4, then 6, then 8 then 10, then 12, etc... Show More
3840 followed by 46080in statistics this is called (perfect) autocorrelation try a harder one... Show More
the sequence is like this! 1×2=22×4=88×6=4848×8=384so..384×10=3840hope this helped!... Show More
