The numbers are increasing by increments of 1 2 3 4 5 ..... and so the next number in the sequence will be 22
Give the simple formula for the nth term of the following arithmetic sequence. Your answer will be of the form an + b.12, 16, 20, 24, 28, ...
Formula for nth termTn = a + (4n - 1) {where a is the first term and n is natural number}
Well, darling, it looks like we're dealing with a sequence where each number is increasing by a prime number. The nth formula for this sequence would be n^2 + n + 7. So, if you plug in n=1, you get 8; n=2 gives you 11; n=3 spits out 16; and so on. Keep it sassy and stay fabulous, my friend!
It is 5n-4 and so the next term will be 21
5n+1
Un = 29 - 9n

Tn = 1 + 3n
20-9x=n
The nth term is equal to 4n.
The nth term of a sequence is the general formula for a sequence. The nth term of this particular sequence would be n+3. This is because each step in the sequence is plus 3 higher than the previous step.
tn = 34 - 9n where n = 1,2,3,...
