an arithmetic sequence, the difference between any two numbers is constant hence it is called the common

difference of the terms. Arithmetic sequence formula is the formula which uses the first term and the common

difference to get the sequence.

Given sequence is arithmetic sequence because,

Common difference between any two consecutive numbers is 4.

So first term, a

Common difference, d = 4

12

So, 12

12

Given, first term, a

Last term, a

n = 12 terms

So sum ->

S
