Question

In the following A. P. find the missing terms in the boxes : 4,box,box,box,box,81/4​

Answer 1

Explanation:

first term a= 4

6th term =81/4

a+5d= 81/4

4+5d =81/4

5d= 81/4-4

5d= (81-16)/4

5d= 65/4

d= 13/4

so second term =4+13/4 = 29/4

third term = 29/4+13/4 = 42/4

fourth term = 42/4+13/4 = 55/4

fifth term = 55/4+13/4 =68/4
