Pls need help ASAP been stressing need in 10 mins

It's choice 2.

Step-by-step explanation:

The nth value is 1 more than twice the previous value

- for example,  15 = 2*7 + 1.

Finally get to swoop in and answer!

Each new value is 1 plus twice the previous value.

First value is 1. Then,

1 plus twice 1 = 3, the second value.

Second value is 3

1 plus twice 3 = 7, so

Third value is 7

and so on (this is merely a check)

i think the answer would be c

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.
