If you mean: 4n-2n = 4 then 2n = 4 and n = 2
Un = 2n - 8 Un = 2n - 8 Un = 2n - 8 Un = 2n - 8
The algebraic expression for "2n 4" would be written as "2n - 4" or "2n + (-4)" in more formal terms. The number 4 is being subtracted from the product of 2 and n. This can be simplified to "2n - 4" for easier understanding and manipulation in algebraic equations.
Sum of interior angles is (2n-4) right angles There are 66 right angles in 5940 degrees So (2n - 4) = 66 2n = 70 n = 35
The first three terms for the expression 2n-6 are obtained by substituting n with consecutive integers. When n=1, the expression evaluates to -4; when n=2, the expression evaluates to -2; and when n=3, the expression evaluates to 0. Therefore, the first three terms are -4, -2, and 0.
