Question

2. Which of the following is a sequence?
a. Tuple
b. Row
C For​

Answer 1

Explanation:

If f(n)−f(n−1)=Constant;  then the sequence is an A.P.

For each option, find f(n)−f(n−1)

Option A:

f(n)−f(n−1)=(an+b)−(a(n−1)+b)

                             =an+b−an+a−b

                             =a→Const

∴  A → is in A.P.

For other options, when we find an expression for f(n)−f(n−1);   we get an expression in variable n; and so is not constant; and hence, not an A.P.

Ans→A

Answer:

a. tuple

Explanation:

probably this could be the answer but u can check in case of any doubt...
