Question

Which term of the A.P.: 5, 11, 17,...is 119?​

Answer 1

Answer:

The 20th term of AP will be 119

Step-by-step explanation:

AP = 5 , 11 , 19 ,.....119

a = 5

d= 11 - 5 = 6

An = 119

since, An = a+(n-1)d

119 = 5 +(n-1) 6

119 - 5 = (n - 1 ) 6

114 = 6 n - 6

114 + 6 = 6n

120 = 6n

n = 120/6

therefore, n = 20
