Answer 1

Answer:

wrong number in the given series is 10

Option A

Step-by-step explanation:

The given series is 3,10,27,4,16,64,5,25,125

on dividing the given series into three groups

(3,10,27),(4,16,64),(5,25,125)

5¹=5

25=5²

125=5³

4¹=4

4²=16

4³=64

3¹=3

3²=9

3³=27

so the correct answer=9

but 10 is given

so, wrong number is 10
