Answer explanation

Check the parts needed to from the recursive formula for the sequence above:

Answer explanation

Given the sequence above choose all of the formulas that could represent the pattern.

Answer explanation

Choose all the patterns from the image above that are Arithmetic Sequences

Answer explanation

Answer explanation

Given the two terms above are and arithmetic pattern which of the following is the explicit formula: Choose all that apply:

• A(n)= -10(n)+62

• A(n)= 52 - 10(n-1)

• f(x)= 62- 10x

• A(n)= 62(-10)^(n-1)

• A₁=62

  An=A_(n-1)-10
