3(2^n-1)
* * * * *
Nearly, but not quite.
The correct answer is 3*2n
36 12 24 48 96

12, 24, and 48 are all multiples of 12 and factors of 48.
Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24.Factors of 48: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48.Factors of 96: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96.GCF (24, 48, 96) = 24
The first 12 multiples are1.62.123.184.245.306.367.428.489.5410.6011.6612.72Hope this helps6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72.
The divisors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48.
If 3 is the first term, then the nth term is [ 3 x 2(n-1) ] .
If 3 is the first term, then the nth term is [ 3 x 2(n-1) ] .
t(n) = 3*2n-1 Or just 3*2n
If you mean: 8 28 48 and 68 then the nth term is 20n -12 and so the next number will be 88
It goes up by (24-16) = 8 each time. The first time is 16. So the nth term is 8n + 8.

Looks like 57: 12+9=21, +9=30, +9=39, +9=48, +9=57.
Had it not been for 64, the nth term would be given by t(n) = 3*n2 However, this cannot be the case because then t(4) would have been 48, not 64.
12 x 12 is the same thing as adding 12 twelve times. 12 x 12 = 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 = 24 + 24 + 24 + 24 + 24 + 24 = 48 + 48 + 48 = 48 +48 +48 ------- = 144
t(n) = (5n3 - 30n2 + 85n - 48)/6 , n = 1, 2, 3, ...
They are: 12, 24, 36 and 48
You are adding by 12. 12 + 12 = 24 24 + 12 = 36 36 + 12 = 48
