The second term in a sequence is 13 the term to term rule is add 6 write an expression in terms of n for the nth term of the sequence

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.

i think the answer is c sorry if it's wrong

substitute,

circle 1 = 5

circle 2 = 20

circle 3 = 44

in this case no matter how you add, you will always get a perfect square..

hence proved

happy to
