The explicit formula for a geometric sequence is a1 * r^n-1
Where a1 is your first term, r is your ratio, and n is the amount of terms you want in the sequence
To solve for the 10th number in the sequence, we simply plug 10 in for n.

Answer:
47
Step-by-step explanation:
arranging in ascending order
33,34,38,42,47,47,48,49,51
total number of terms=9
median=(9+1)/2=5th term=47
Write an equation to show all elements:
Cost of 4 lots of b (beads) + cost of 4p (pendants) = $18.80
Put values in;
9.29 + 4p = 18.80
4p = 18.80 - 9.20
4p = 9.60
p = 2.40 cost of each pendant
I believe the answer is 2. i hope this helps
