"Six Days Seven Nights", a 1998 movie starring Harrison Ford and Anne Heche.
d = n + 7 and (n + 17)/(d - 6) = 2 so (n + 17)/ n + 7 - 6 = 2 (n + 17)/(n + 1) = 2 2n + 2 = n + 17 n = 15 and d = 22 Check n + 17 = 32, d - 6 = 16, 32/16 = 2 Original number is 15/22
int main (void) { printf ("%d+%d=%d\n", 6, 7, 6+7); return 0; }

for a integer n, we call d the divisor of n if d divides n without leaving a remainder. So, for example, 49/7=7 and 7 is a divisor or a factor of 49. ( n=49, d=7 in this case) Since 7 is the divisor the reciprocal of 7 is just 1/7. In general is n is a divisor, 1/n is the reciprocal.

The nth term of an AP with initial term a (= u{1}) and common difference d is given by: u{n} = a + (n - 1)d In this case: a = 6 d = (12 - 6) = 6 → u{n} = 6 + (n - 1)6 But this can be simplified: u{n} = 6 + (n - 1)6 = 6 + 6n - 6 = 6n
n + 7 = 4*6 n + 7 = 24 n = 24 - 7 = 17.

Suppose n is a whole number and the fraction is 1/d where d is also a whole number.Then n / (1/d) = n * (d/1) = n*dFor example, 7 / (1/5) = 7*(5/1) = 7*5 = 35

The sequence given is an arithmetic sequence where each term increases by 6. To find the nth term, you can use the formula for the nth term of an arithmetic sequence: ( a_n = a_1 + (n-1)d ), where ( a_1 ) is the first term and ( d ) is the common difference. Here, ( a_1 = 7 ) and ( d = 6 ). Thus, the nth term can be expressed as ( a_n = 7 + (n-1) \times 6 = 6n + 1 ).
