Answer
$a_1=7$,$a_2=11$,$a_3=15$,$a_4=19$, $a_5=23$,$a_6=27$
Work Step by Step
Initial term, $a_1=7$ and common ratio $d=4$.
Now, we need first six terms such as:
$a_1=7$,$a_2=7+4=11$,$a_3=11+4=15$,$a_4=15+4=19$, $a_5=19+4=23$,$a_6=23+4=27$
Hence, six terms are: $a_1=7$,$a_2=11$,$a_3=15$,$a_4=19$, $a_5=23$,$a_6=27$
