Question

Write the sequence with $n^{th}$ term and $a_n=3+4n$.

• A. $7,11,15,19,...$
• B. $7,12,19,24,...$
• C. $7,11,16,19,...$
• D. $7,12,17,23,...$

Answer 1

The correct option is A $7,11,15,19,...$

Here $a_n=3+4n$
$\therefore a_1=3+4\times 1=7$
$a_2=3+4\times 2=11$
$a_3=3+4\times 3=15$
$a_4=3+4\times 4=19$

Hence, the given sequence is $7,11,15,19,...$
