Answer:

5.2,10.4,15.6,20.8,26

Step-by-step explanation:

Given that,

Common difference of an AP, d = 1.3

First term, a = 5.2

We need to find the first 5 term of the sequence.

Second term,

[tex]a_2=a+(n-1)d\\\\a_2=5.2+(2-1)(5.2)\\\\a_2=10.4[/tex]

Third term,

[tex]a_3=5.2+(3-1)(5.2)\\\\a_2=15.6[/tex]

Fouth term,

[tex]a_4=5.2+(4-1)(5.2)\\\\a_4=20.8[/tex]

Fifth term,

[tex]a_5=5.2+(5-1)(5.2)\\\\a_5=26[/tex]

The AP is : 5.2,10.4,15.6,20.8,26
