Question

The nth term of 2,5,8,11,.....Is
A.3n
B.3n+1
C.3n-1
D.3n^2-1.

Answer 1

Answer:

C.3n-1

Step-by-step explanation:

2,5,8,11........

here, a=2. & d=3

an=a+(n-1)d

an=2+(n-1)3

an=2+3n-3

an=3n-1

Answer 2

Answer:

C. 3n - 1

Step-by-step explanation:

According to the question

The 1st term, a = 2

Common difference, d = 3

We know that,

The nth term, $a_{n}$ = a+(n - 1)d

                               = 2+(n - 1)3

                               = 2 + 3n - 3

                               = 3n - 1

Hence the nth term will be 3n - 1.
