Ans. The wrong term is 253

Answer 2

Answer:

The wrong term is 253.

Step-by-step explanation:

Hey Mate,

Series => 3, 5, 15, 50, 123, 253

(i) [3 + 1³ + 1] + 0 = 5

(ii) [5 + 2³ + 2] + 0 = 15

(iii) [15 + 3³ + 3] + 5 = 50

(iv) [50 + 4³ + 4] + 5 = 123

So, now.

(v) [123 + 5³ + 5] + 10 = 263

The Logic is (Number + n³ + n) + 0, + 0, + 5, + 5, + 10, +10, + 15, + 15....

So,

The wrong term is 253.
