Answer:
7n - 1
Step-by-step explanation:
notice that the difference between adjacent terms is 7.
so nth term is given by:
nth term = first term + (n-1)×difference (n is any number)
= 6 + (n-1)7
= 6+ 7n -7
= 7n - 1

Answer:
s = (SA - 1)/ar
Step-by-step explanation:
from the question SA = ars + 1 we want to make s the subject of the formulae
so from,
SA = ars + 1
SA- 1 = ars
divide both sides by ar
(SA - 1)/ar = ars/ar
(SA - 1)/ar = s
therefore ,
s = (SA - 1)/ar
