Question

Which of the following can be the nth termof an AP ? 1) 4/n+2 2)4n+5 3)2n2+3 4)n2+5n

Answer 1

Answer:

b) 4n+5

Step-by-step explanation:

If A is the first term and D is the common difference of an AP, it's nth term is given by,

Tn = A + (n-1)D = Dn + (A-D).

i.e., the power of n will be always 1.

so, here, only b) has n with power 1, so it is the answer.
