# Sequence

Write the first 7 members of an arithmetic sequence: a1=-3, d=6.

a1 =  -3
a2 =  3
a3 =  9
a4 =  15
a5 =  21
a6 =  27
a7 =  33

### Step-by-step explanation:

${a}_{1}=-3$
${a}_{2}={a}_{1}+6=3$
${a}_{3}={a}_{2}+6=9$
${a}_{4}={a}_{3}+6=15$
${a}_{5}={a}_{4}+6=21$
${a}_{6}={a}_{5}+6=27$
${a}_{7}={a}_{6}+6=33$ Did you find an error or inaccuracy? Feel free to write us. Thank you! ## Related math problems and questions:
