Find the first 4 terms of the sequence given by the recursive definition:
c_na_n-1 - 3, a_1= 2

  none of the above

Step-by-step explanation:

It appears your definition is of an arithmetic sequence with first term 2 and common difference -3. Each term is 3 less than the one before it. The first 4 terms of that sequence are ...

  2, -1, -4, -7 . . . . . matches no offered choice

The first choice is described by the formula ...

  an = n -3

It appears that the problem's author mixed up recursive and explicit formulas.

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b
