find term of given A.P 10, 13,16,19.....20th term

$\huge\mathtt{{\colorbox{silver}{ANSWER}}}$

First Term (a) ➡ 10

Common Difference (d) ➡ 13-10 = 3

Therefore the 20th term will be,

= a + (n-1) d

= 10 + (20 - 1)3

= 10 + (19) 3

= 10 + 57

= 67

Therefore the 20th term of the AP is 67

Answer 2

Answer:

20th term = 67

Step-by-step explanation:

Here,

First term, a = 10

Common difference, d =(13-10) = 3

Then, 20th term = a + (n - 1) d

Since n = 20

Therefore, a + (n - 1) d = 10 + (20 - 1) 3 = 10 + 19×3 = 10 + 57 = 67
