Answer 2

Answer:

• 16th term

Step-by-step explanation:

Given

• 4 , 9 , 14 , 19 .. ?

To find

• Which term of the AP is 79 ?

Solution

➔ nₜₕ term of an AP = a + (n - 1)d

Where:

• a = first term
• d = common difference
• n = term

Here:

• a = 4
• d = (9 - 4)
• d = 5

Substituting we get:

• Tₙ - 79 = a + (n - 1)d = 79
• 4 + (n - 1)d = 79
• 5n = (79 - 4 + 5) = 80
• n = 16

Hence, the 16th term of the given AP is 79.
