Final answer:
To find the fourth term, substitute n = 4 into the given expression. The fourth term is 41. To find the fifth term, substitute n = 5 into the given expression. The fifth term is 61. To find the 52nd term, substitute n = 52 into the given expression. The 52nd term is 1001.
Step-by-step explanation:
To find the fourth term, substitute n = 4 into the given expression. An = 20n - 39
Fourth Term: A4 = 20(4) - 39 = 80 - 39 = 41
To find the fifth term, substitute n = 5 into the given expression. An = 20n - 39
Fifth Term: A5 = 20(5) - 39 = 100 - 39 = 61
To find the 52nd term, substitute n = 52 into the given expression. An = 20n - 39
52nd Term: A52 = 20(52) - 39 = 1040 - 39 = 1001
