Answer: (a) 11
(b) 74
Step-by-step explanation: To find the second term , it implies that the value of n = 2 , what you need to do is to substitute n = 2 into the given formula
i.e 3(2^2) - 1
3(4) - 1
12 - 1
= 11
Also to find the fifth term, it means n = 5
substitute that into the formula and you get 74
