Question

Write an Arithemetic Sequence with common difference 4,What is the 11th term of the sequence

Answer 1

Answer:

• 41.

Step-by-step explanation:

Let the A.P's first term be 1.

Then, common difference (d) is 4.

⇒ 1, 5, 9, 13, 17

Now, the 11th term will be:

⇒ a + (n - 1)d

⇒ 1 + (11 - 1)4

⇒ 1 + (10)4

⇒ 1 + 40

⇒ 41

∴ 41 is the 11th term of the sequence.

General term of an A.P:

• a + (n - 1)d

Sum of n terms of an A.P:

• n/2[2a + (n - 1)d]

Sum of n terms of an AP with last term:

• n/2[a + l)

Where we have:

• a = First term
• d = Common difference
• l = last term
• n = term number
