Answer:
The required expression which can be used to find the nth term in the sequence is:

Hence, the fourth option i.e. 2n+3 is the correct option.
Step-by-step explanation:
Given the sequence
5, 7, 9, 11,...
An arithmetic sequence has a constant difference 'd' and is defined by
computing the differences of all the adjacent terms
The difference between all the adjacent terms is the same and equal to
d = 2
So
Thus, the nth term of the sequence is

substitute a₁ = 5 and d = 2 in the sequence


Therefore, the required expression which can be used to find the nth term in the sequence is:

Hence, the fourth option i.e. 2n+3 is the correct option.
Answer:
= 403
Step-by-step explanation:
the sum to n terms of an arithmetic series is
=
(a + l) ← a is the first term and l the last term
here a = - 5 and l = 67 , then
=
(- 5 + 67) = 6.5 × 62 = 403
