Answer 1

Answer:

hlo

your answer is here !

Step-by-step explanation:

Hey there !!

A.P. 7 , 13 , 19 , ...... , 205

a = 7

d = 13 – 7 = 6

An = 205

As we know,

An = a + (n–1) d

205 = 7 + (n–1) 6

=> 205 – 7 = (n–1) 6

=> 198 = (n–1) 6

=> n–1 = 198 / 6

=> n–1 = 33

=> n = 33 + 1

=> n = 34

Thus, total no. of terms is 34.

Answer 2

Answer:

the series has 34 terms.

Step-by-step explanation:

this question is from arithmetic progression......

a=7

d=a²-a=13-7=6

Considering there are n terms in this A.P. = an=205

205=7+(n−1)6

198=(n−1)6

33=(n−1)

n=34
