Question

Two number series are given below; each follows a different pattern. Neither of the series contains any wrong term. Series I: 121, (m - 5), 211, 301, 409, 535 Series II: 145, 155, (n + 4), 235, 315, 425 Which of the following statement(s) is/are true? (

Q: Answer-Two number series are given below; each follows a different pattern. Neither of the series contains...

Series I 121 18 1 139 139 18 4 211 211 18 5 301 301 18 6 409 409 18 7 535 So, m - 5 139 m 144 Series II 145 1 9 155 155 2 25 184 184 3 42 235 235 4 64 315 315 5 85 425 So, n 4 184 n 184 - 4 180 Statement I m n 144 180 324. 324 18 18, so 324 is a multiple of 18. So, statement I is true. Statement II k 180 - 144 36. Sum of digits of k 3 6 9. 9 is not a prime number. So, statement II is false. Statement III 20 of n 20 of 180 36. n - 20 of n 180 - 36 144. m 144, which is equal to 144. So, statement III is true.

I Sum of the values of 'm' and 'n' is a multiple of 18. (I
I Difference between the values of 'm' and 'n' is 'k', where the sum of the digits of k is a prime number. (II
I Value of 'm' is 20% less than the value of 'n'.
