You first have to do distributive property to get -18r-1=14-r, now get teh smallest r to the other side, in this case add 1r to both sides to get -17r=14, now add 3 to both sides to get -17r=17, now divide by -17 to leave r by itslef and get teh answer of r=-1
Hope this helps

Answer:
In bold below.
Step-by-step explanation:
a) Arithmetic sequence with common difference 3 and first term = 2:
nth term = 2 + 3(n - 1)
= 3n -1.
b) Similar to above with common difference 2 and first term = 9.
nth term = 9 + 2(n - 1)
= 2n + 7.
