Answer:
Step-by-step explanation:
So Lets do this question!!!!
This is Arithematic Progression
Here, a₁ = 3, a₂ = 7, a₃=11
Using a₁ and a₂ the common difference(d) is 4.
We have to find a₁₆
So,
a₁₆ = a₁ + (n - 1) d
⇒ a₁₆ = 3 + (16 - 1) 4
⇒ a₁₆ = 3 + 15×4
⇒ a₁₆ = 3 + 60
⇒ a₁₆ = <u>63</u>
Hence, the answer is 63 toothpicks.
its 63
