Find the 10th term
FORMULA: Tn=a+d(n-1)

T₁₀ = 23

Step-by-step explanation:

The nth term of an arithmetic sequence is

= a + (n - 1)d

where a is the first term and d the common difference

Here a = - 4 and d = T₂ - T₁ = - 1 - (- 4) = - 1 + 4 = 3 , then

T₁₀ = - 4 + (9 × 3) = - 4 + 27 = 23

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

answer: 10 turtles

step-by-step explanation: as turtles have four legs so 4.10=40 therefore birds are 4 which sue counted
