It will be 25cm long Since it growing 10cm every 2 years it must be growing 5cm every year 10/2=5/1 To find total growth in 5 years multiply the cm it grows every year by the number of years so 5yearsX 5cm =25cm

Find the 22nd term of the following sequence: 5, 8, 11, ... 63 71 14 68

Wittaler [7]

68 is the 22nd term of the following sequence.

Step-by-step explanation:

The given sequence is with the same common difference between the two consecutive number in the series thus it is said to be the Arithmetic progression ( AP).
For finding the nth term in the AP we have a formula tn = a + (n-1) × d
Here a is the first term , n is the number of the term to be founded and d is the common difference between the two consecutive number in the series.
Thus here tn = 5 + ( 22 - 1 ) × 3.
On subtracting we get tn = 5 + (21 ) × 3
On multiplying we get tn = 5 + 63
After adding we get tn = 68. It is the 22nd term in the given series.
