Answer 2

Answer:

The 7th number of square will have 22 matchsticks.

Step-by-step explanation:

Here,

the number of matchsticks are in Arithmetic Progression.

Therefore, a = 4 and d = 7 - 4 = 3

Now, we can find the 7th number of square as follows:-

tn = a + ( n - 1 )d

t7 = 4 + ( 7 - 1 )3

t7 = 4 + ( 6 )3

t7 = 4 + 18

t7 = 22
