Question

The first four terms of an $A.P.$ whose first term is $2$ and the common difference is $2$ are:

• A. $-2,0,2,4$
• B. $2,4,8,16$
• C. $2,4,6,8$
• D. $2,5,8,11$

Answer 1

Answer: (C)

$2,4,6,8$

First term of an AP $\left(a\right)=2$
Common difference $\left(d\right)=2$
Therefore, the first four terms are:
$a_1=2$
$a_2=2+2$
$a_3=2+2\times 2=6$
$a_4=2+2\times 3$
Therefore, the first four terms are: $2,4,6,8$
