Question

if t17 =34 is an a.p.then find s33​

Answer 1

Sum of 33 numbers will be 1122

Step-by-step explanation:

Since 17th term is 34 We can write it as

1. a+16d = 34

In A.P sum of n terms = N/2(2a+(n-1)d)

So, sum of 33 terms will be = 33/2(2a+32d)

From equation 1, 2(a+16d) = 2(34) = 68

S33 = 33/2(68) = 1122
