what is the arithmetic sequence for 2, 5, 8, and 11 please help asap
we have
a1=2
a2=5
a3=8
a4=11
so
a2-a1=5-2=3
a3-a2=8-5=3
a4-a3=11-8=3
the common difference d is equal to d=3
the general equation for this arithmetic sequence is equal to
an=a1+d(n-1)
we have
a1=2
d=3
substitute
an=2+3(n-1)
an=2+3n-3
