Question

find the mentioned terms of given A. P 10,13,16,19 [20th term ]​

Answer 1

Answer:

a = 10

d = 3

an = a +(n-1)d

a20 = 10 +19(3)

a20 = 10 + 57

a20 = 67

Answer 2

$\huge\tt\green{SolUtioN:-}$

Given that:-

→ first term a = 10

→ common difference d = 13 - 10 = 3

→ nth term = 20

Then according to questions:-

using formula :

$\huge\boxed{an = a+ (n - 1)d}$

a20 = 10 + ( 20 - 1) 3

a20 = 10 + 19 × 3

a20 = 10 + 57

a20 = 67

$\huge{\boxed{\boxed{\boxed{\red{ a20 = 67}}}}}$
