Sixth 215=6^3 - 1

Answer 2

Given:

215,124,63,___,7,0

To Find:

Find the missing term

Solution:

We are given a series that follows a predefined pattern that is followed by every term of the series, and we need to find the missing term by identifying the pattern and finding the value of the missing term.

To find the pattern we can use various mathematical operations or a combination of them such as addition, subtraction, square, cube root, etc.

We are given 215,124,63,___,7,0, the pattern followed in this series is that the cube of a number is taken and 1 is subtracted from that cube and the pattern starts with a cube of 6 and goes in the descending order,

$215=6^3-1\\124=5^3-1\\63=4^3-1$

So the next term will also follow the same pattern that will be,

$=3^3-1\\=27-1\\=26$

Hence, the value of the missing term is 26.
