Question

find the 5th term of the following A.p. 3 8 13 18

Answer 1

Answer:

23

Step-by-step explanation:

tₙ=a+(n-1)d

t₅=3+(5-1)5

    =3+20

         =23

Answer 2

Given,

A.P. = 3, 8, 13, 18, ---

To find,

The 5th term of the A.P.

Solution,

The fifth term of the A.P. is 23.

We can easily solve this problem by following the given process.

We know that in an A.P. the common difference is found by subtracting the first term from the second term.

Common difference(d) = Second term - first term

d = 8-3

d = 5

The first term(a) is 3.

We have to find the fifth term. So, the n will be 5.

The formula for finding a term is a + (n-1)d.

Fifth term = a + (n-1)d

Fifth term = 3 + (5-1) 5

Fifth term = 3 + 4×5

The fifth term = 3 + 20

The fifth term = 23

Hence, the fifth term is 23.
