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