Step-by-step explanation:

Since we have given that

Number of gamblers played black jack, roulette and poker = 5

NISA [10]

Answer:

Step-by-step explanation:

t2 = a*r

t2 = 6

t5 = a*r^4

t5 = 162

162/6 = ar^4 / ar

r^3 = 27

r = 3

6 = a*3

2 = a

             r - 1

n = 5

a = 2

r = 3

Sum = 2(3^5 - 1)

           =======

Sum = 242
