Question

(3) In an A. P. if a = 1, d = 3 then find t11
​

Answer 1

Answer:

31

Step-by-step explanation:

In the given sequence,

a= 1. d= 3. t11 =?

tn= a+(n-1)d

t11= 1+(11-1)3

t11= 1+ (10)3

t11 = 1+30

t11= 31

Answer 2

ANSWER : 31

EXPLANATION :

Given

a= 1 and d = 3

To find

• t11

As we know that,

$a_{n} = a + (n - 1)$

SO,

→ a11 = 1+(11-1)3

→ a11 = 1 +(10)3

→ a11 = 1 + 30

→ a11 = 31.
