The sum of the AP=816

Step-by-step explanation:

a_1=a=6,a_2=12

a_n=96

d=a_2-a_1=12-6=6

nth term of A.P is given by

a_n=a+(n-1)d

Where a_n=Last term

a=First term

d=Common difference

n=Total number of terms of AP

Using the formula

96=6+(n-1)(6)

96-6=6(n-1)

90=6(n-1)

n-1=\frac{90}{6}=15

n=15+1=16

Sum of nth terms of A.P is given by

S_n=\frac{n}{2}(a+a_n)

Substitute the values then we get

S_n=\frac{16}{2}(6+96)

S_n=8\times 102=816

Hence, the sum of the AP=816
