In an arithmetic sequence, if you are given a3=93 and a5=135, find a=100. Must show work to receive full credit.
Elanso [62]

The 100th term of the sequence is 2130.

<h3>How to calculate the value?</h3>

a3 = a + 2d = 93

a5 = a + 4d = 135

Compute both equations

(4d - 2d) = (135 - 93)

2d = 42

d = 42/2 = 21

a + 2d = 93

a + 2(21) = 93

a + 42 = 93

a = 94 - 42 = 51

100th term will be:

= a + 99d

= 51 + 99(21)

= 51 + 2079

= 2130

horsena [70]

Answer:

No

Step-by-step explanation:

His answer is incorrect.  If we round the dimensions, 3.76 m is almost 4 m, and 5.49 m is almost 5.5 m.  4 × 5.5 = 22.  So his answer should be close to 22 m².
