Question

the first,secondand fourth terms in a proportion are 31,112,217 respectively find the third term

​

Answer 1

Answer:

60.0625

Step-by-step explanation:

Let the third term be x.

We know that in a proportionate series, the product of mean terms is equal to the product of extreme terms.

Mean terms = 112 and x

Extreme terms = 31 and 217

So, 112*x = 31*217

=> 112x = 6727

∴ x = 6728/112 => 60.0625

Thus, the third term in this proportionate series is 60.0625.
