Question

if a=11 and d=1.5 then find t2 and t3​

Answer 1

Step-by-step explanation:

Option D - t_3=14t3=14

Step-by-step explanation:

Given : For an A.P., if a = 11 and d= 1.5.

To find : The value of t_3t3 ?

Solution :

The nth term of A.P is given by,

t_n=a+(n-1)dtn=a+(n−1)d

Where, a=11 is the first term

d=1.5 is the common difference

n=3 is the number of terms

Substitute the value,

t_3=11+(3-1)1.5t3=11+(3−1)1.5

t_3=11+(2)1.5t3=11+(2)1.5

t_3=11+3t3=11+3
