Step-by-step explanation:
the n th term of an arithmetic sequence is
=
+ (n - 1)d
given = 3 and
= 10, then
= 3 + d = 10 ⇒ d = 10 - 3 = 7
= 3 + 7(n - 1) = 3 + 7n - 7 = 7n - 4
the sum to n terms of an arithmetic sequence is
=
[2
+ (n - 1)d ]
= [(2 × 3) + 7(n - 1) ]
= (6 + 7n - 7 )
= (7n - 1)
= n² -
n
