An arithmetic sequence begins 4, 11, 18, 25, 32, .... Find the common difference d for this sequence. d = Find a formula for the nth term a_n of the sequence. an = Find the 35th term of the sequence. a_35 =

Solution

The sequence is 4, 11, 18, 25, 32,…..

a) Common difference = d = 7

b) nth term = a_n = a₁ + (n - 1)*d

c) a₃₅ = a₁ + (35 - 1)*d = 4 + 34*7 = 242
