1.Find the first 4 terms in each sequence.

a) t_n = 3(-2)^n-1

b) t₁ = 11, t₂ = 3, t_n = 8t_n-1 + t_n-2

2.Use Pascal's Triangle to expand and simplify the following binomial: (4x + 7)⁵

3.Complete chart for each sequence

4, 12, 36, -7, -2, 3, Is the sequence geometric or arithmetic? Explain your thought process. Recursive formula General formula (simplified if possible) The 10th term The sum of the first 10 terms
