What The Nth Term Of 3 4 5 6 7 Sequence

What the nth term of 3 4 5 6 7 sequence

 

ANSWER :

The nth term is An = n + 2.

STEP BY STEP EXPLANATION :

An = A1 + (n - 1) × R

An = 3 + (n - 1) × (4 - 3)

An = 3 + (n - 1) × 1

An = 3 + n - 1

An = n - 1 + 3

An = n + 2

• Testing...

A1 = 1 + 2 = 3

A2 = 2 + 2 = 4

A3 = 3 + 2 = 5

A4 = 4 + 2 = 6

A5 = 5 + 2 = 7

Therefore , the nth term is An = n + 2.

OK.
