Answer 3

hm

Answer 4

when i substitute n = 3 i get 62 which isn't one of the answers

Answer 5

I'm really wondering if this is correct lol n = 1

I'm thinking the sequence goes like this:

3∙7(1)−1=20


3∙7(2)−1=41

Answer 6

right, and when you substitute n = 3 you get 62

may i see a screenshot of the original question ? there might be a formatting problem

Answer 7

oh wait!

Answer 8

ok, if the n is part of the exponent that changes things

Answer 9

3*7^(2) is 147, so you're right

Answer 10

for future reference, if you see something in the exponent, you write it like

x^(exponent here)

to avoid confusion
