Question

Write the arithmetic progression when first term $a$ and common difference $d$ are $a=4;d=-3$

Answer 1

Arithmetic progression is the sequence of numbers such that the difference between the consecutive numbers is constant.

If the first term is $a$ and the common difference is $d$ then the sequence is $a,a+d,a+2d,a+3d,...$

Given that first term $a=4$ and

common difference $d=-3$

Therefore, the sequence is $4,4+(-3),4+2(-3),4+3(-3),...$

$⟹4,1,-2,-5,...$ is the required arithmetic progression.
