Answer 2

Required Answer:-

Given AP:

• 1, 4, 7...

To Find:

• The 10th term of the given AP.

Solution:

In the given AP,

→ First term = 1

→ Common difference = 4 - 1 = 3

We know that,

→ Nth term of an AP = a + (n - 1)d

Where,

• a = First term and,
• d = Common difference.

So, the tenth term of the given AP will be,

= a + (10 - 1)d

= 1 + 9 × 3

= 1 + 27

= 28

★ Thus, the tenth term of the given AP is 28.

Answer:

• 10th term of the AP is 28.

AP Formulae and Symbols:

• First term = a
• Common difference = d
• Nth term = a + (n - 1)d
• Sum of first n terms = n/2[2a + (n - 1)d]
• nth term - mth term = (n - m)d
• If l is the last term of a finite AP, then nth term from end = l - (n - 1)d
• If there are odd number of terms in AP (say n), then middle term = (n + 1)/2th term.
• If there are even number of terms in AP (say n), then middle terms are - n/2th term and (n/2 + 1)th term.
