Question

Find the wrong terms of the series 9, 29, 65,126, 217, 344

Answer 1

Answer:

Answer is 29

Step-by-step explanation:

Let us take a closer look at the series

9,29,65,126,217,344

Now, let us take a closer look at the terms

9 = 2³ + 1

65 = 4³ + 1

126 = 5³ + 1

217 =6³ +1

344 = 7³ + 1

So, the series are a representation of n³ + 1 where n is a natural number

but, in case of 29,

we see,

29 = 3³ + 2

which is the odd one.

Correct term would have been - 3³+1 =28
