Answer:

  1. 9
  2. 16
  3. 23
  4. 30 

Step-by-step explanation:

Insert 4 arithmetic means between 2 and 37.

First Step :

《First term 》a1 = 2

《Last term》an = 37

《No. of all terms》 n = 6

Find the common difference (d).

To find the common difference (d).

Use the formula:

an= a1+ (n-1) dan=a1+(n−1)d

Substitute.

37= 2+ (6-1) d37=2+(6−1)d

37= 2+ 5d37=2+5d

(37= 2+ 5d)-2(37=2+5d)−2

37-2= 5d37−2=5d
