Example 1 Write the first three terms in each of the following sequences defined by the following: (ii) an = (๐‘› โˆ’ 3)/4 We need to find first three terms a1, a2, a3 an = (๐‘› โˆ’ 3)/4 putting n = 1 in (1) a1 = (1 โˆ’ 3)/4 = (โˆ’2)/4 = (โˆ’1)/2 Putting n = 2 in (1) a2 = (2 โˆ’ 3)/4 a2 = ( โˆ’1)/4 Putting n = 3 in (1) a3 = (3 โˆ’ 3)/4 a3 = 0/4 a3 = 0 Hence first three terms are โˆ’1/2, โˆ’1/4, 0
