Answer:33 and 47
Step-by-step explanation:
because it is not the right pattern
The wrong element in the series is 33
Step-by-step explanation:
=> The given series is the list of prime numbers from 23
=> Prime numbers are those numbers having only 2 factors and those are 1 and the number itself "OR" those numbers which are only can be divided by 2 numbers and those numbers are 1 and the number itself.
=> Let us check the numbers given in the series,
(i) 23 can only be divided by 1 and 23.
(ii) 29 can only be divided by 1 and 29.
(iii) 31 can only be divided by 1 and 31.
(iv) 33 can be divided by 1, 3, 11 and 33.
(v) 41 can only be divided by 1 and 41.
(vi) 43 can only be divided by 1 and 43.
(vii) 47 can only be divided by 1 and 47.
As we can observe that all numbers are only divided by 1 and number itself but 33 has 4 factors.
Therefore 33 is the wrong number in the series.
