The tenth term of ap -3, -1, 1,3 ...., is

Answer 1

Hello, Buddy!!

||Required Solution||

-3,-1,1,3.... are in AP

a = -3

a1 = -1

a2 = 1

a3 = 3

• d = a1-a

Where, d is the common difference.

→ -1-(-3)

→ -1+3

→ 2

• Sum of n terms = a+(n-1)d

→ -3+(10-1)2

→ -3+(9)2

→ -3+18

→ 15

• 10th Term of the AP ☞ 15
