Please help In the sequence below the first term is 2 and each term after the first is k times the preceding term where k is a c

Maslowich

Apparently k=6. It doesn't say it in the question, but I'll assume that you had a mistype and forgot to say that the second term is 12.
Anyway,
The nth term of a geometric sequence is $a_{1}* k^{n-1}$ . Thus, the 52nd term would be $2* k^{51}$ and the 50th term would be $2* k^{49}$ When you divide the two, the 2's would cancel out and k^49 would cancel out, leaving you with 1 on the bottom and k^2 on the top. As we said at the beginning, k=6, so our answer is just 6*6=36.

Gala2k [10]

Step-by-step explanation:

Total number of outcomes = 52 , since each deck consists of 52 cards

probability = Number of favorable outcomes/ Total number of outcomes

a) Number of favorable outcomes = Number of club cards = 13

P(club) =13/52 = 1/4

b) Number of favorable outcomes = Number of red cards = 26

P(red card) = 26/52 = 1/2

c) Number of favorable outcomes = Number of cards that are not hearts = 39/52 = 3/4
