a. 26 b. 35 c. 34 d.27​

Answer 1

Answer:

The number of terms are (c) 34.

Step-by-step explanation:

Here 7, 13, 19, ....., 205 are making an A.P., where,

a = 7 and d = 13 - 7 = 6, and, $a_{n}$ = 205.

Now, using, $a_{n} = a + (n-1) d$

205 = 7 + (n - 1) 6 {We find n}

6(n - 1) = 198

n - 1 = 198/6 = 33

n = 33 + 1 = 34.
