Nth term problem

[glossy gale]

so im rll bad at nth term i wouldnt mind some help rn cuz i need to pass up this hw asap 😭

omg this too

[amber rivet]

7n - 5

for first

6n -5

for 2nd

you start by counting how much its increasing from term to term

so for the first one

9-2 = 7

16 - 9 = 7

so its increasing 7

it starts at 2

take 2- 7 that is - 5

so that means when n = 0 its - 5
