Question

3,15,35,63,99....? What is the next number

Answer 1

Heya!

Logic :- logic is that they are the multiples of consecutive odd numbers.

First term      : 1 × 3 = 3

Second term : 3 × 5 = 15

third term     : 5 × 7 = 35

Fourth term  : 7 × 9 = 63

Fifth term      : 9 × 11 = 99

Therefore,

Sixth term = $\boxed { 11 \times 13 = 143}$

Hope it helps! :)

Answer 2

Answer:

The missing term in the given pattern/series is found to be 143.

Step-by-step explanation:

Let $x$ be the next term in the given series.

By carefully analysing the given series, we can say that each term in the series is the product of the two consecutive odd numbers.

We can prove this by showing the factors of the given terms of the series given to us:

$3=1\times3$

$15=3\times5$

$35=5\times7$

$63=7\times9$

$99=9\times11$

Now, To find the next term in the given series, we can take the product of 11 and 13 to get the correct answer:

$x=11\times13$

$x=143$

So, the correct answer is 143.
