State True or False:
5, 6, 7, 8, 9,....... is an arithmetic progression.
True
An arithmetic progression is a sequence of numbers in which the difference between any two consecutive terms is constant.
Given,
first term, a1 = 5
second term, a2 = 6
common difference, d = a2 - a1 = 6 - 5 = 1.
Therefore, 5, 6, 7, 8, 9,... is an arithmetic progression with common difference 1.
