The equation which represents the nth term in the sequence is:
an: 5n-12
Given:
a3 = 3, a4 = 8 and a5 = 13 and a = 18.
we know the common difference in Arithmetic sequence is:
aₙ = a+(n-1)d.
a is the first term
d is the common difference
in the given sequence we have:
a = 18 and
d = 5
substitute the values.
aₙ = 18+(n-1)d.
aₙ = 18+(n-1)5.
aₙ = 18+5n-5
aₙ = 5n-12
Hence we get the answer.
