Question

the nth term is 3n+2 work out the first three terms

Answer 1

Solution :-

As expression for the nth term

= 3n + 2

→ First term, n = 1

= 3(1) + 2

= 3 + 2

= 5

→ Second term, n= 2

= 3(2) + 2

= 6 + 2

= 8

→ Third term n = 3

= 3(3) + 2

= 9 + 2

= 11

First three terms

= 5 , 8 , 11

Now we are able to see that :-

The common difference is same for two consecutive terms .

So it is Arithmetic Progression.

Answer 2

Answer:

Step-by-step explation for 2+2

It might seem hard but all you got to do is get one hand of yours then pull up 2 fingers then pull up anthor 2 fingers the count them all like this: 1 finger 2fingers 3 fingers and then 4 fingers and there is your answer have fun doing maths . So now you know 2+2=4  now try this:

$\sqrt[100]{420} + \int\limits^a_b {x} \, dx - \lim_{n \to \infty} a_n$
