Question

What is the common difference of the sequence 8, 4, 0, -4, -16?

Answer 1

`\large \mathfrak{Solution : }`

Common difference of an Arithmetic progression can be found out by subtracting the preceding term from that given term.

i.e

• 
  `common \: \: difference = 4 - 8`
• 
  `common \: \: difference = - 4`

therefore, the common difference of the above Arithmetic progression is -4 .
