1 squared, 2 squared, 3 squared etc so the next 3 terms are 36,49 and 64.
Divide by three. 4, 4/3, 4/9

8/3, 8/9 and 8/27.
10, 48 and 116. These are derived using the cubic generator: Un = (-4n3 + 27n2 - 47n + 30)/3 for n = 1, 2, 3, ...
1 squared, 2 squared, 3 squared etc so the next 3 terms are 36,49 and 64.
1, -3, -7
-1 -3
Each number is three times the previous number.
Divide by three. 4, 4/3, 4/9
2.6 and 3.
You are dividing by 3 each time, so the next 3 numbers are 8, 8 over 3 and 8 over 9.
Divide by three. 4, 4/3, 4/9
To find the first three terms, plug 1, 2, and 3 in for n:Term 1: 2(1) - 1 = 1Term 2: 2(2) - 1 = 3Term 3: 2(3) - 1 = 5
1 = * 2 = ? 3 = *?
Which sequence? Oh, that one! The first three terms are 1, 2 and 72.
