Answer:

136

Explanation:

This is an arithmetic sequence

The formula is an = a1 + f × (n-1)

n= the number we are trying to find = 37

a= the number in any given space on the sequence

a1= 460

f= the common difference between the numbers

f= -9 because you subtract 9 from each to get the number

a37= 460-9(37-1)

a37= 460-9(36)

a37= 460- 324

a37= 136

Given :


\\

  • The first three terms of a sequence are 460, 451, 442


\\

To Find :


\\

  • 37th term of sequence = ?


\\

Solution :


\\

Clearly these three terms are making an arithmetic sequence, with :

  • First term, a = 460
  • Common difference, d = 451 - 460 = - 9


\\

Now, we have to find 37th term of sequence =
\tt a_(37)


\\

Now, we know that :


\large \underline{\boxed{\bf{a_(n) = a + (n-1)d}}}


\\


\tt : \implies a_(37) = a + (37-1)d


\tt : \implies a_(37) = a + 36d


\\

Now, by substituting values of a and d :


\tt : \implies a_(37) = 460 + 36 * (-9)


\tt : \implies a_(37) = 460 - 324


\tt : \implies a_(37) = 136


\\

Hence, value of 37th term of given sequence is 136.
