39. Find the odd man out

b) 2,4,8,16

c) 12,24,36,48

d) 10,13,16,19

Answer: 2,4,8,16

Reason: The second sequence 2,4,8,16 is in geometric progression and

not in arithmetic progression.Hence the answer is 2,4,6,8

b) 121

c) 242

d) 352

Reason: Sum to n no of terms in a geometric progression is Sn = a(1 –

rn)/(1-r) . Applyting a = 3, n = 5 and r = 3 we get S5 = 3(1 – 3 5)/(1 –

3) = 363. Hence the correct answer is 363.

ii) 2,4,8

iii) 10,20,40

iv) 1,1//2,1/4

b) 2,4,8

c)10,20,40

d)1,1//2,1/4

Reason: All the four sequences are in geometric progression.However

the last series 1,1//2,1/4 is an infinite series. This is because the

common ratio for this series, which is 1/2 is lesser than 1.Hence the

correct answer is 1,1//2,1/4
