THE EXPLICIT FORMULA Use the following arithmetic sequence and the formula an= a1 + (n - 1)d to answer the questions below. 123, 116, 109, 102, 95, ...

Part I: Find the value of each of the following: 21 = 123 and d=-17

Part II: Find the explicit formula. Show your work.

Part III: Use the explicit formula you found in Part II to find the value of the 100th term in the sequence, a100. Show your work.

State whether each sequence is arithmetic or geometric, and then find the explicit and recursive formulas for each sequence. (10 points: 5 points each)

step-by-step explanation:

i dont know

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
