Find nth term of Arithmetic Sequence a = 9, n=78, and d=2

Steps to find nth term of arithmetic sequence:

nth term of arithmetic sequence formula:-

a_n = a + (n-1) *d

where:

• a_n is the nth term
• a is first term
• n is total number of terms
• d is common difference

Input values are:-

a = 9

n = 78

d = 2

Put values into formula

a₇₈ =a + (n-1) *d

a₇₈ = 9 + (78-1) *2

a₇₈ = 163

The steps that should be followed to calculate the Nth Term of Arithmetic Sequence a = 9, n=78, and d=2 is listed below for your knowledge. Refer to them while finding the nth term of AP: 

• At the initial stage, you have to understand the given terms to find the nth term of the Arithmetic sequence i.e., a = 9, n=78, and d=2.
• Now, you have to apply the formula of arithmetic progression nth term ie., an =a+(n-1)d and put the values in it. 
• After simplifying the expression, you will get the output as a5=163.
