Answer 2

How many shaded squares are in term 1 ? (You have to count them)

Answer 3

12

Answer 4

now, for each choice, replace n with 1 and figure out what the formula predicts
For example, for choice (1) we do
4*1+12
which simplifies to 4+12 or 16
12 is not 16, so that choice does not work.
try the others

Answer 5

would it be 2?

Answer 6

\[4(1) + 8 = 12\]

Answer 7

And why do we need to have the 1 replacing the \(n\)?

Answer 8

because n is the Term number

Answer 9

oh okay. so would choice 2 be the correct answer?

Answer 10
