Show that the sequence is arithmetic Find the common differe

Show that the sequence is arithmetic. Find the common difference and write out the first four terms. {s_n} = {n + 3} The sequence is arithmetic with a common difference of d = The first four terms of the sequence are s_1 = s_2 =, s_3 = and s_4 =

Solution

sn = n+3

s1 = 4 ; s2 = 5 ; s3 =6 ; s4 = 7

common difference , d = 5 -4 =1
