Answer: Here IS THe ANswer

Step-by-step explanation:

Answer 2

Answer:

The number of terms in the given AP = n = 39

Explanation:

Given AP = 7,16,25,....349​

First term = a = 7

Common difference = d = a₁ - a₂

= 16 - 7

= 9

Last term = nth term = aₙ = 349

By the formula, we have

aₙ = a + (n – 1) d

Substituting the values, we get:

= 349 = 7 + (n -1) 9

⇒ 349 - 7= 9 (n-1)

⇒ 342 = 9 (n-1)

⇒ n-1 = 342/9

⇒ n-1 = 38

⇒ n = 38 + 1

⇒ n = 39

Hence, the number of terms = n = 39

Hope you understood.
