Question

2. The nth term of a progression is 3n + 4. Is the pattern of numbers, so formed, in A.P.? If so,
find its 6th term.
​

Answer 1

Answer:

Given that :

n = 3n + 4

Let n = 1

3(1) + 4 = 7

Let n = 2

3(2) + 4 = 10

Let n = 3

3(3) + 4 = 13

Let n = 4

3(4) + 4 = 16

Now the A.P. form is 7, 10, 13, 16.....

Here

common difference = 10 - 7 = 13 - 10 = 16 - 13 = 3

Hence the given pattern is in A.P.
