Answer:

The value of A33 = 398 ....

Explanation:

Given:

The Arithmetic sequence A1,A2,A3,A4 ,62, 74, 86, 98

What is the value of A33?

T(n) =a +(n-1)d

where d = 12

n = 8

T(8)=a+(8-1)*12

T(8)=a+7*12

T(8)=a +84= 98

a=98-84

a= 14

Now,

T(33)= 14+(33-1)*12

=14+(32)*12

= 14+384

T(33)= 398

The value of A33 = 398 ....
