Question

A number 3 more than 5th term of sequence3,5,7,.........is?​

Answer 1

Answer 14

Step-by-step explanation:

: it is an ap  whose first term is 3 and cd is 2 i.e 5-3=2

an=a+(n-1)d=>3+(5-1)2=>3+8=11

3 more than 5 th term is 11+3 =14

ans =14

Answer 2

The number 3 more than 5th term of sequence 3 , 5 , 7 , . . . . is 14

Given :

The sequence 3 , 5 , 7 , . . . .

To find :

The number 3 more than 5th term of sequence

Concept :

If in an arithmetic progression

First term = a

Common difference = d

Then nth term of the AP

= a + ( n - 1 )d

Solution :

Step 1 of 3 :

Write down the given sequence

Here the given sequence is

3 , 5 , 7 , . . . .

Step 2 of 3 :

Find 5th term of the sequence

The given sequence is an arithmetic sequence

1st term = a = 3

Common Difference = d = 5 - 3 = 2

So the 5th term of the sequence

= a + ( 5 - 1 )d

= a + 4d

= 3 + ( 4 × 2 )

= 3 + 8

= 11

Step 3 of 3 :

Find the number 3 more than 5th term of sequence

Hence the required number

= 11 + 3

= 14
