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.
Answer:
w=1 5/24
Step-by-step explanation:
7/9-4/3w=-5/6
-4/3w=-5/6-7/9
-4/3w=-15/18-14/18
-4/3w=-29/18
w=-29/18:(-4/3)
w=29/18*(3/4)
w=29*3/18*4
w=29/6*4
w=29/24
w=1 5/24
Answer:
