Find the first three terms of the sequence below. T n = n 2 + 3 n + 4

9,14,19

Step-by-step explanation:

You seem to be giving the expression 2n+3n+4.

Now simplify

An = 5n+4

Fill in n

5(1) +4

5(2) +4

5(3)+4

After solving and simplifying you see 9, 14 and 19 are the first 3 terms.

  32

Step-by-step explanation:

Students will own "fewer than 2" if they own 0 or 1 jackets.

  15 students own 0 jackets.

  17 students own 1 jacket.

Then 15 +17 = 32 students own fewer than 2 jackets.
