Answer 2

13th Term is 6.5

Step-by-step explanation:

Given:

First term (a) = 0.5

Difference = Second term - first term

Difference (d) = a2- a1

Difference (d) = 1.0 - 0.5

                      = 0.5

Calculation:

Find the value of A(n), where n = 13

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

       = 0.5 + (13 - 1) x 0.5

       = 0.5 + (12) x 0.5

       = 0.5 + 6

       = 6.5

Therefore, the thirteenth term of given A.P. is 6.5
