Answer:
b+54
Step-by-step explanation:
Since Jackie has 54 fewer beads than Sally, Sally has 54 more beads than Jackie. Since b is the number of beads that Jackie has, then Sally's beads would be 54 more than that thus it would be b+54.

remember that (a+b)/c=(a/c)+(b/c)
so

=

also remember


=

=

a=1
b=0
c=2
d=3
The numbers are 11 and 5
There product is 55
The explicit formula for a arithmetic sequence is a_n = a_1 + (n - 1)d.
We want to find a_21.
a_21 = 17 + (21 - 1)(10)
a_21 = 17 + (20)(10)
a_21 = 17 + 200
a_21 = 217
The 21st term is 217.
