Question

for an A.P if a=2 and d=2.5 then which is the seventh terms?

Answer 1

Answer:

a=2

d=2.5

a7=a+6d

=a+6(2.5)

=2+15

=17

a7=17

please mark me brilliant.

Answer 2

Given,

In an Arithmetic progression (A.P.) :

First term = a = 2

Difference = d = 2.5

To find,

The seventh term of the A.P.

Solution,

We can solve this mathematical problem by using the following mathematical process:

As per the principles of an arithmetic progression with first term a and difference d, a nth term of the AP is represented as:

A(n) = a + (n-1)d

So, on using this formula, we get;

The seventh term of the A.P.

= A(7)

= a + 6d

= 2 +6(2.5)

= 17

Hence, the seventh term of the A.P. is 17.
