The nth term of a sequence is 3n2 - 1
a) find the second term of the sequence:
b) find the fifth term of the sequence.

 (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

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
