Answer to Problem 17WE

The value of t21 the arithmetic sequence is 61 .

Explanation of Solution

Given information:

  t7=19,t10=28

Formula used:

The nth term of an arithmetic sequence is given by the following expression:

  tn=t1+(n1)d

Where,

First term: t1

Common difference: d

Calculation:

The equations are formed as:

  t7=t1+(71)d19=t1+6d

  t1+6d=19  ... (1)

And

  t10=t1+(101)d28=t1+9d

  t1+9d=28  ... (2)

Now, t1 is calculated by taking subtraction of both eqns.

  t1+6dt19d=19+283d=9d=3

Now, put value of d=3 in eq. (1):

  t1+6d=19t1+6(3)=19t1=19+18t1=1

Now, value of t40 the arithmetic sequence is calculated as:

  t21=t1+(211)dt21=1+20(3)t21=160t21=61
