22. for the sequence 3, 10, 17, 24, , write the explicit equation for this sequence, then
find the 18th term.

see explanation

Step-by-step explanation:

Note the common difference d between consecutive terms

d = 10 - 3 = 17 - 10 = 24 - 17 = 7

This means the sequence is arithmetic with n th term

= a₁ + (n - 1)d

Here a₁ = 3 and d = 7, thus explicit formula is

= 3 + 7(n - 1) = 3 + 7n - 7 = 7n - 4, thus

= (7 × 18) - 4 = 126 - 4 = 122

all teachers

step-by-step explanation:

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.
