it says find the next 3 terms
3, 4, 7, 11, 18
does anyone know how to solve this?

add the previous two numbers together, to get the next in sequence
3+4 = 7
4+7 = 11
7+11 = 18
etc...etc...

The pattern simply adds the last two numbers to get the next one.
3 4 7 11 18
3+4=7
4+7=11
11+7=18
So the next term would be
18+11= 29
and 29+18= 47
29+47=76

Just by looking at it, it seems two consecutive numbers added together makes the next number.
For instance, the first two numbers, 3 and 4 add to 7, the third number. 4 and 7 add to 11. Following this pattern, add the last two number to get the next number in the series:
11 + 18 = 29
3, 4, 7, 11, 18, 29
Then,
18 + 29 = 47
and
29 + 47 = 76
So, the last three terms are:
29, 47 and 76

Add the previous two terms. 3+4=7, 4+7=11, 7+11=18.
Now your answers:
11+18=29
18+29=47
29+57=76

Looks like two Options
The other one is...
Do you see a the pattern?
4 -3 = 1
7 -4 = 3
11 - 7= 5
18 -11 = 7
? - 18 = 9 ? = 27
? - 27 = 11 ? = 38
? - 38 =13 ? = 51

3+4=7 4+7=11 7+11=18
11+18=29 18+29=47 29+47=76
ALWAYS TRY TO FIND ANY KIND OF RELATION BETWEEN NUMBERS

Third number i.e. 7 = sum of first Number+ Second Number
= 3+4
Fourth numberi.e 11= sum of second number+ Third number
= 4+7
Fifth numberi.e 18= sum of third number+ fourth number
= 7+11
Sixth numberi.e 29 = sum of fourth number+ fifth number
= 11+18
seveth numberi.e 47 = sum of second number+ Third number
= 18+29
Eigth numberi.e 76 = sum of second number+ Third number
= 29+47
Therefore next three numbers will be 29, 47, 76
Checkhere the series is
3, 4, 7, 11, 18, 29, 47, 76,...............

It's a variation of the Fibinachi sequence.
Each digit is the sum of the previous 2 digits.
29, 47, 76

Yeah, it's a modified Fibonacci series.
But, since I'm an ornery sumbitch, I'd probably put down 5 and then work up the Lagrange polynomial that would yield 5 for an index of 6
