Which two numbers does √61 lie between on a number line? 7.7 and 7.8 7.8 and 7.9 7.9 and 8.0 8.0 and 8.1

B, 7.8 & 7.9; Since the square root of 61 is 7.81024, then that means it would lie just above 7.8 in the number line.

√61=7.81025

so I i would say it is B

for b its (t) and c its (d)

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
