The first three terms for the expression 2n-1 can be found by substituting n with the first three consecutive integers. When n=1, the expression becomes 2(1)-1 = 1. When n=2, the expression becomes 2(2)-1 = 3. When n=3, the expression becomes 2(3)-1 = 5. Therefore, the first three terms are 1, 3, and 5.

Well, darling, the first term is 1, the second term is 3, and the third term is 5. It's as simple as that, honey. Just plug in n=1, n=2, and n=3 into the expression 2n-1 and you've got your answer.
To find the first three terms, plug 1, 2, and 3 in for n:
Term 1: 2(1) - 1 = 1
Term 2: 2(2) - 1 = 3
Term 3: 2(3) - 1 = 5

You use the FOIL method. First terms Outer terms Inner terms Last terms.
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.
What is the sum of the first 27 terms of the geometric sequence -3, 3, - 3, 3, . . . ?
no it is a binomial. terms in an algebriac expression are separated by addition or subtraction ( + or -) symbols and must not be like terms. then just count the terms. one term = monomial, 2 terms = binomial, 3 terms = trinomial. More than 3 terms are usually just referred to as polynomials.
