Answer 2

Correct question is "What is the next term of the series 21, 22, 46,141,568 ?"

Answer:

Required next term is 2845.

Step-by-step explanation:

Given, 21, 22, 46,141,568

We want to find next term of the series.

This is a problem of General inteligence part of Mathematics.

Here all terms are maintaining a sequence.

$21 \times 1 + 1 = 22 \\ 22 \times 2 + 2 = 46 \\ 46 \times 3 + 3 = 141 \\ 141 \times 4 + 4 = 568$

This the sequence of the series.

So required next term will be $568 \times 5 + 5 = 2845$

This is a Mathematics problem.

Some important Mathematics formulas:

${(x + y)}^{2} = {x}^{2} + 2xy + {y}^{2} \\ {(x - y)}^{2} = {x}^{2} - 2xy + {y}^{2} \\ {(x + y)}^{3} = {x}^{3} + 3 {x}^{2} y + 3x {y}^{2} + {y}^{3} \\ {(x - y)}^{3} = {x}^{3} - 3 {x}^{2} y + 3x {y}^{2} - {y}^{3} \\ {x}^{3} + {y}^{3} = {(x + y)}^{3} - 3xy(x + y) \\ {x}^{3} - {y}^{3} = {(x - y)}^{3} + 3xy(x - y) \\ {x}^{2} - {y}^{2} = (x + y)(x - y) \\ {x}^{2} + {y}^{2} = {(x - y)}^{2} + 2xy \\ {x}^{2} - {y}^{2} = {(x + y)}^{2} - 2xy \\ {x}^{3} - {y}^{3} = (x - y)( {x}^{2} + xy + {y}^{2} ) \\ {x}^{3} + {y}^{3} = (x + y)( {x}^{2} - xy + {y}^{2} )$
