What is an Equation ?

An equation is a mathematical statement formed when two algebraic expressions re equated by an equal sign.

On the base of the given data

Let the first and second number is x and y

Then the third , fourth , fifth and sixth number is (x+y) , (x+2y) ,(2x+3y),(3x+5y)

The first term is 112

There are six numbers in the sequence

The last term is given by the equation

3x+5y = 2021

3* 112 +5y = 2021

5y = 1685

y = 337

Therefore the sequence is 112 , 337 , 449,786 , 1235 , 2021
