Question

given the first term and the common difference of an arithmetic sequence find the 52nd term and the explicit formula. did I do this right ?

Answer 1

41) A52 = -10206

42) - 320

43) -276

44) 10200

Explanation:

41) A1 = -6, D = -200

An = a1 + (n - 1) d

We have to use the above formula to find the 52nd term.

A52 = -6 + (52 - 1) -200

= -6 + 51*-200

= -6 - 10200

A52 = -10206

42)

37 + -7(52 -1)

37 + -7(51)

= 37 - 357

= - 320

43)

30 + -6(52 -1 )

= 30 + -6(51)

= 30 - 306

= -276

44)

0 + 200(52 -1)

= 200(51)

= 10200

Thank you.

Hope you will understand the concept.

Thank you.
