The corresponding equation, is solve n when :- 2(n - 4) = -8 2n - 8 = -8 2n = -8 + 8 = 0 n = 0
nth term= 6 + (n-1) (2)

The coefficient is 1.6
The coefficient is 16.
It's the value of a variable, eg 2 is the coefficient of n in the expression 2n
Un = 2n - 8 Un = 2n - 8 Un = 2n - 8 Un = 2n - 8
By definition a term is the basic unit of algebra which must contain 3 parts - a sign, a coefficient and a variable (e.g., 2n [+ sign implied, coefficient '2' and variable 'n'] and -7d). In the expression 2n-4-7d then, there are 2 terms.
2n + 8 = -142n = -22n = -11
If 'n' is 8, then (2n - 7) is 9 .
It appears that the nth term is (8 + 2n).- For n=12, (8 + 2n) = (8 + 24) = 32 .- For n=77, (8 + 2n) = (8 + 154) = 162.
The coefficient of the given term is -8
-8
Answerno solutionProcedureAssume the numbers are:2n, 2n+2, 2n+4, 2n+6, 2n+8, 2n+10Summation = 12n + 30 = 60012n = 597n = not integer numberno solution
Substituting n=4 into the expression 25 - 2n, we get 25 - 2(4) = 25 - 8 = 17.
