Question

Write the first three terms of the AP when a and d are as given below:

$a=5,d=3$, then first three terms are $5,8,11$
If true then enter $1$ and if false then enter $0$

Answer 1

Here
$a_1=a=5$
$a_2=a+d=5+3=8$
$a_3=a+2d=5+2\times 3=11$
$\therefore 1^{st}$ three terms of an A.P. are

$5,8,11,....$
