The n is replaced by the term number;
where there is no operator (add, subtract, multiply, divide, etc), a multiply is implied (as the multiply symbol could be confused with a letter x);
so the 10th term is:
10 x 10 - 8 = 100 - 8
= 92
77
The formula is 6n + 7 where n is the nth term So 8th term would be (6 x 8) + 7 = 48 + 7 = 55
Can not be determined without the starting number in the series or n sub1

No, it will be a formula, because "the nth term" means that you have not defined exactly which term it is. So, you make a formula which works for ANY term in the sequence.

The nth term is 0.37n+0.5 and the 10th term is 4.2
n = 100 + 7 = 107
The formula is 6n + 7 where n is the nth term So 8th term would be (6 x 8) + 7 = 48 + 7 = 55

For {12, 15, 18} each term is the previous term plus 3; a general formula for the nth term is given by t(n) = 3n + 9. For {12, 24, 36} each term is the previous term plus 12; a general formula for the nth term is given by t(n) = 12n.

Tenth term of 5n + 1 = 5*10 + 1 = 51
If by using the formula: nth term = n2+2 the sequence is 3 6 11 18 27 38 51 66.Then it follows that by using the same formula the sequence is III VI XI XVIII XXVII XXXVIII LI LXVI in Roman numerals.
